INSTRUCTIONS TO AUTHORS
(Updated September 12, 2025)
1. General Information
1.1. Biochemistry (Moscow) is a monthly international journal established by the Russian Academy of
Sciences and published concurrently in Russian and English.
1.2. Biochemistry (Moscow) publishes works in all fields of biochemistry, as well as conceptually
important works on biochemical aspects of related fields (molecular biology, biophysics, bioorganic
chemistry, microbiology, immunology, physiology, neurobiology, gerontology, biomedical sciences, etc.)
aimed to understanding molecular and cellular bases of biological processes. The journal also covers new
experimental techniques in the field of biochemistry, theoretical advances relevant to biochemistry,
reviews of modern biochemical research topics and mini-reviews. The journal does not consider purely
phenomenological works which describe changes in biochemical parameters or markers of biological
processes without connection with the mechanisms that caused these changes or are results of such
changes, as well as works on cloning and expression of individual genes (including those in transgenic
animals and plants) and materials analyzing genomic polymorphisms.
1.3. Finished original works presenting new experimental results are considered for publication, as well as
methodological works providing description of new methods of biochemical research, theoretical
materials describing new principles and approaches for solving some or other biochemical problems.
Papers based on investigation of a well-known object isolated from alternative sources are not considered
for publication.
“Short communications” section publishes short experimental articles of a preliminary or priority
nature that require accelerated publication and have received the highest ratings from reviewers. In the
cover letter the authors have to justify necessity of accelerated publication of the material. Turnover time
is 1 month.
The journal publishes Reviews invited by the Editorial Board (or offered by the authors and
approved by the Board) on the most newsworthy problems of biochemistry and related sciences. The
review articles must meet the following requirements: 1) the authors must have their own works on the
subject of the review; 2) the list of references should include works published on this topic during the last
5 years; 3) the review should not be a retelling and, sometimes, a word for word quotation of the
fragments from the earlier published works, it should contain a critical analysis of the cited materials and
the suggested concept, the authors’ view on the problem that prompted them to write this review. The
Editors and reviewers are strictly vigilant about plagiarism; 4) reviews must not include previously
unpublished material and may be rejected in peer-review. Since there is no detailed description of the
research methods and results and there is no statistical analysis, the evaluation of this data is impossible.
The section “Discussion” provides opportunity for the authors to comments and provide critical
remarks about the works published earlier in the journal, to propose a new hypothesis. The section has a
polemic nature and publishes responses of the parties affected by the publications.
1.4. The journal is included in the Bibliographic Databases Web of Sciences, Biochemistry and
Biophysics Citation Index, Biological Abstracts, BIOSIS Database, Chemical Abstracts, Chemical Titles,
Current Contents/Life Science, Excerpta Medica, Index Internacional de Cardiologia, Index Medicus
(MEDLINE/PubMed), International Abstracts of Biological Sciences, The ISI Alerting Service, Science
Citation Index, Science Citation Index Expanded, SCOPUS, Compendx; RISC (Russian Index of
Scientific Citation). The journal is included in the list of peer-reviewed scientific publications of the
Higher Attestation Commission (Russia).

e-mail (affiliation); 4) abstract; 5) keywords; 6) short title of the manuscript (running title); 7) the
manuscript text including the list of references, tables, figure captions.
The title should be as short and informative as possible and should not contain abbreviations.
If the authors of the article are employees of different institutions, the institutions should be
numbered and superscript numbers indicating the authors’ affiliations should follow the authors’ last
names; the author responsible for correspondence with the Editors should be indicated by asterisk to the
right of the number. For each of the authors the complete name of the institution with the postal code, city,

major significant results of the work and conclusions from it.
The list of Keywords should not contain more than 15 items.
A short Running title should be given on a separate line after the title.
When using non-standard abbreviations, the section Abbreviations should be added. The manuscript text
should be divided into sections: 1) Introduction; 2) Materials and Methods; 3) Results; 4) Discussion (if
discussion is short, the results and discussion may be combined); 5) Conclusions; 6) References.
The Introduction briefly describes background of the problem with imperative review of the works,
in which similar or relevant studies have already been conducted, and objective of the study is formulated.
The Materials and Methods section should be as short as possible, but adequate for reproduction of
the experiments; the section should also include materials, reagents and equipment used in the work with
indication of the company and manufacturer country, e.g., glycerol (Sigma-Aldrich, USA), a JEM 100C
electron microscope (JEOL, Japan) (if the company name is mentioned repeatedly in the body of the
article, the name of the country should be omitted). Only new procedures should be described in detail; the
previously published and well-known methods should be referred to the list of references, indicating the
author and/or the name of the method (e.g., the protein concentration was determined by the Bradford
method [7]). If the method is not widely known, it is advisable to set out its principle and specify the
author.
References to the methods such as “nuclease was measured by the method [7]” or “according to
[7]” are not allowed (the reference cannot be an independent member of a sentence).
The section Results should present the data in figures and tables; the experiments which do not
need documentation are described in the text. In this section, the results should not be discussed; the
authors can limit themselves by explaining causal relationships between the experiments described.
The section Discussion should contain interpretation of the results (but not their repetition) and
comparison with the previously published data. It is advisable to illustrate the major results with a simple
and visual scheme.
If necessary, the manuscript closes with the Conclusions section which is separate from the
Discussion section.
In accordance with the Journal participation in the International Committee on Publication Ethics
(COPE), the authors have to introduce at the end of the manuscript some phrases demonstrating adherence
to the international ethical standards. Examples of the relevant items in the final part of the manuscript are
given below.
1) Contribution of each author to the study and preparation of the manuscript should be
indicated (“Contributions” section). For example: John P. Smith and Anna Do conceived and supervised
the study; Carl Broide carried out experiments; Ivan P. Petrov discussed the results of experiments
with input from all authors; Lui Jing and Haifeng Yong wrote the manuscript, and Franklin
Parada edited the manuscript.
2) If the work was supported by any organization, in the item “Funding” it should be
indicated what foundation and grant supported this study and each part of the work separately, if the
sources of funding are different. The full names of institutions and sponsoring organizations should be
given.
3) In the “Acknowledgments” item the authors can present information about any assistance
in conducting the work and preparing the article: about useful discussions, assistance of colleagues,
providers of materials, scientific data, computer equipment, devices; about conducting researches at
collective use centers; about assistance in the technical preparation of the text. Description of the role of
each author in preparation of the publication is preferred.
4) In the item “Conflict of Interests” the authors declare the presence or absence of conflict
of interests in financial or any other field. This item is obligatory.
5) The item “Compliance with Ethical Standards” is also obligatory. If studies were
conducted on animals, this item states: “All procedures performed in studies on animals were in
compliance with ethical standards of the institution in which the studies were conducted and with the
approved legal acts of the Russian Federation and international organizations”.
If the study was conducted with the participation of humans, the item “Compliance with Ethical
Norms” states: “All the procedures carried out in the research with participation of humans were in
compliance with the ethical standards of the National Research Ethics Committee and with the Helsinki
Declaration of 1964 and its subsequent changes or with comparable ethics standards. Informed voluntary
consent was obtained from every participant of the study”.
If the manuscript does not contain descriptions of studies involving humans or using animals
which has been performed by any of the authors, the item “Compliance with Ethical Norms” states: “This
article does not contain descriptions of studies performed by the authors with participation of humans or
using animals as objects”.
The items “Conflict of Interests” and “Compliance with Ethical Standards” are merged in the
article in the “Ethics declarations” subsection.
6) If the manuscript contains identification information about participants of the study, the
following position should be included in the item “Informed Consent”: “From all participants whose
personal information is used in this manuscript the additional written voluntary consent was obtained”.
The list of References should be as short as possible but should contain references for all
fundamentally important recent publications on this problem. In the journal the sequential numbering
system of citations is adopted, i.e., in the text the order number of the cited source [in square brackets]
corresponds to the number in the list of References. Authors should carefully check the sequence of the
reference numbering in the text and their number in the bibliography. It is not allowed to include
references to websites in the list of references; it is necessary to refer to publications of the authors
offering these electronic resources (programs/databases). If such publications are absent, the reference is
given in the text in the same way as to other unpublished materials (for example, the Database of Bacterial
Carbohydrate Structures, csdb/glycoscience.ru/bacterial).
References to unpublished data are not permitted. Citation of personal communication should
provide the person’s full name and affiliation. Duplications should be avoided in the list of references, as
well as citation of retracted papers.
The list of References is printed as a separate section of the manuscript with the names and initials
of all the authors, title of the cited article, and output data. In addition, it is advisable to give doi of the
article. Below the examples of references to journals, books, collected articles, and dissertations are given.

For authors using the EndNote system the Editors provide a style that supports formatting citations
in the text and the list of references. The style file can be found on the journal websites
http://protein.bio.msu.ru/biokhimiya and https://biochemistrymoscow.com in the sections for authors.
3.3. The volume of experimental article should not exceed 20 typewritten pages, including references,
tables, and figures (three figures are equivalent to one page) with figure captions, and abstract; the number
of figures and tables should not exceed eight; short communications should not be more than 12 pages
(including no more than 4 figures and/or tables); mini-reviews should not exceed 16 pages (including no
more than 5 figures); reviews should not be more than 35 pages (including no more than 8 figures);
communications in the “Discussions” section can be up to 4 pages.
3.4. Text files should be submitted in Microsoft Word format (version 6.0 and later); Times New Roman
font of 12-point size should be used for the entire manuscript file. The text should be in one column, with
line spacing of one and a half intervals, with 3 cm left margin, left alignment, and without word
hyphenation. In the page, it should be no more than 30 lines.
In the text formatting the use of italics, bold, subscript and superscript indices, Greek and
mathematical symbols (12-point Symbol font) should be according to the Journal style.
The style of the text material should be simple: without programmed headlines, inserts,
templates, references to literary sources (hyper-references); without increase in line and letter spacing;
without the use of templates, “normal” style should be selected. This particularly applies to the
“References”, because programmed sequence numbers disappear when transferred to the publishing
program.
Authors should not use such functions of the Word program as “Bookmark”, “Note”, “Footnote”,
“Endnote”, because the publishing program misinterprets them. If the text contains a footnote (or
endnote), then the authors should print “{Footnote}” immediately after the sentence or paragraph with its
number and then directly the footnote text.
If the “Review” function was used during manuscript preparation, then before saving the file the
“Review” function should be deactivated and the function “Accept all changes in the document” should be
used.
3.5. Tables should be provided in cases when the data cannot be presented in the text.
Each table is prepared on a separate page and has its own title. Column headings should be
provided; dimension of the values should be separated with comma. The column headings should be as
short as possible, values easily deducible from the available ones (e.g., difference or percent) should not
be given. Repetition of the same data in the text, tables, or figures is not allowed.
Tables are accepted only in the Word format (doc, docx). If the tables contain graphic inserts, these
inserts should be sent as separate high-quality graphic files.
3.6. Figures with corresponding legends should be included in the file of the manuscript, and each figure
should be located just after the paragraph, where it was mentioned for the first time.
In addition, figures should be presented as separate files meeting the following requirements:
for schemes and graphs without half-tone inserts: files in the “tiff”, “jpg” or “pdf”
format, in Black-and-White mode (Line-art, Bitmap). Pixelized (raster) images are accepted only in the
“tiff” or “jpg” formats;
for half-tone drawings or graphs with half-tone inserts: files in the “tiff”, “jpg” or “pdf”
format, in half-tone Black-and-White mode (Grayscale). Pixelized (raster) images are accepted only in the
“tiff” or “jpg” formats;
for color drawings: files in the “tiff”, “jpg” or pdf” format, in the color mode CMYK (for
color printing), RGB (for color drawings in the electronic version). Pixelized (raster) images are accepted
only in the “tiff” or “jpg” formats.
independently of the figure type, it should have high real resolution: at least 300 “dpi”
for half-tone illustrations; no less than 600 “dpi” for line and mixed (half-tone/line) illustrations.
Pixelization of images in raster graphic formats should not be rough. Lines of figures must be of at least 3
points thick. Excessively small symbols (letters, numbers, icons, etc.) should be avoided. Pixelized (raster)
drawings should not be inserted into a Word document or translated into “pdf” format, because this
impairs their quality;
figures should have size corresponding to their informativeness. The size of a figure for
one column should not be less than 8 cm; for two columns no less than 17 cm. Figures should not be
excessively large;
vector illustrations should not contain point fillings, such as “Noise”, “Black & white
noise”, “Top noise”. For vector drawing, all used fonts should be included in the file;
fonts inside the figures should be selected from the “Arial” set with the size of 9 points;
scanning images from books and other printed publications should be avoided, since such
files give a poor quality when printed and are unreasonably large.
General requirements for preparing plots, diagrams, and formulas:
plots should contain designations of the coordinate axes (the parameter measured and the
unit of measurement), as well as of curves and other details. Inscriptions on the axes are made along them
in “Arial” font with a capital letter, the unit of measurement is separated with a comma and not with
brackets (e.g., Eluent volume, ml). The lines inside the figure should be numbered (the numbers should be
in italics: 1, 2, etc.), and in the subtitle (not within the figure) explanation should be given to each line.
Experimental points should preferably be presented as hatched and non-hatched circles, squares, triangles,
or diamonds. Individual curves can also be presented as solid, dashed, or dotted lines. All curves should be
clearly depicted with the lines of thickness (usually 3 points) that makes it possible to reduce the figure to
the final size in the journal. Axes of coordinates in most cases must be displayed with black (not gray)
lines. Background of the plot or diagram should be white, without coordinate grid lines (except the cases
when a different color of the background color or the grid are necessary for proper comprehension);
in diagrams and photographs individual elements (columns, gel tracks, etc.) should be
numbered in italic Arabic numerals (1, 2, etc.) and in the figure caption (not within the figure) each
number should be explained. If in addition to Arabic numerals, introduction of Roman numerals (I, II,
III, etc.) is required, these numerals must be printed in the direct outline;
if the figure consists of several parts (diagrams, plots, schemes, protein structures,
photographs, including electropherograms), they should be marked with lower-case letters (a, b, c, etc.)
using the “Times” headset larger than the main text. These letters should be placed in the upper left
corners of the respective parts. In the figure caption an explanation should be given to each part of the
figure;
“ChemWindows” software is used to type chemical equations in the text; long complex
mathematical expressions should be submitted as figures without legends in one of the adopted formats
(“pdf”, “tiff”, or “jpg”). Each equation is given as a separate file, the name of which corresponds to the
equation number in the manuscript. These files should be prepared using the guidelines for drawings given
above. The “Equation Editor” function should be used only for extended mathematical equations (for
both numbered and given in the text). Short expressions (designations) appearing directly in the text, such
as G, TS, K
m
,
should be typed as the rest of the text, using the main functions of “Word”. Simple
expressions requiring “kerning” (simultaneous use of both subscript and superscript located one under the
other) should be typed using only the subscript and superscript functions of “Word”
(e.g., NH
3
+
), and the
“kerning” will be performed by the layout maker during the typesetting.
These requirements are essential,
because the publishing program misunderstands the data obtained using the “Equation Editor” function;
mathematical expressions should not exceed 8.5 cm in width. Larger expressions should
be divided into several lines. Only Times New Roman and Symbol fonts should be used for mathematical
expressions. If equations are submitted as pixelized (raster) images, they should be in Black-and-White
(Line-art, Bitmap) mode. Such images should have very high real resolution (pixelization should not be
rough). Pixelized (raster) images should not be inserted into a Word document or converted to “pdf”,
because it can impair their graphic quality;
presentation of amino acids, nucleotides, and other sequences often requires the exact vertical
positioning of the elements. To prevent errors and avoid tedious proofreading of large amounts of
information, the authors should submit such materials in a form suitable for reproduction.
We draw attention to the general conditions for publication of the illustrations:
the inscriptions and symbols in the figures can be different in the Russian and English
versions when translated, therefore, for photographs and figures where the inscriptions are imposed onto a
complex, non-one-toned background, it is desirable to provide the second version without the text and all
symbols; in other illustrations the inscriptions should be placed avoiding their contact with the other parts
of the illustration. Authors may also prepare themselves versions of the figures with English inscriptions;
the figure should have the title and an informative subscription that makes its meaning
understandable without reference to the text: conditions specific to the particular experiment are indicated;
reference to the basic text may be given only to avoid repetitions and obscurities;
color illustrations are published free of charge to authors, if they are to be placed only in
the electronic version of the article and in the printed version of the journal they will be presented in
black-and-white. However, the authors should bear in mind that in the printed version with black-and-
white figures the captions will be the same as in the color electronic version, thus, color indications in the
figure captions should be avoided. Authors need to select colors preventing the loss of informativity at the
black-and-white printing. It is advisable to mark the colored lines of the plots with designations, numbers,
or special symbols, or to use different line styles for each color. It is desirable also to mark colored areas
in illustrations with different designations or special symbols, but not with the same symbols of different
colors. If the color separation of the areas is approximately in the same color tone, then it is desirable to
draw a thin line as a border between them. If there are many color areas in similar color tones, it is
desirable to additionally mark the areas with symbols or hatching. It is desirable to make all inscriptions
and designations not colored, but black or white, depending on the support;
if the electronic version of the article contains several color figures, it is possible to
publish in the printed version these figures in color with charge, or to publish them in black-and-white free
of charge. Publication in the printed version only some of the color figures in color is not possible;
it is advisable to print copies of the prepared figures to make sure that they look good in
printed form: all elements of the figure should be clearly visible when printed, the background should be
clean, the inscriptions and numbers should be easy to read. It is often rather difficult to assess the figure
quality only by its look on the computer screen;
if the authors use illustrations or tables from other publications (including their own) in
the manuscript, they should request permission from the Copyright holders of these publications for
reprinting or using the materials.
Failure to follow these rules for preparing graphical material leads to sending it back to the
authors for modification and to delay in the manuscript publication.
3.7. Additional materials to articles. Supplementary materials (audio- and video files, presentations,
additional tables and figures, etc.) could be submitted provided the authors are primary copyright holders
of these materials and permission was not granted to any person/organization (except Publishers) for their
use, or the authors have documented permission to use these materials for publication and distribution in
the journal. Supplemental materials should be stand-alone items. Supplemental materials should not
include information essential for understanding of the paper. Supplemental materials are not edited and
processed, and are published as submitted by authors. Files containing supplementary materials should be
numbered in order, for example ESM_1.jpg, «ESM_2.pdf, ESM_3.xls. There should be reference to
Supplementary materials in the text (“additional data are presented in Online Resource 1”, “…as shown in
Table in Online Resource 2”). Supplementary materials are considered as an integral part of the paper and
the same requirements are applied as for the main manuscript. Supplementary materials are published only
in online version of the journal at https://www.springer.com.
3.8. We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or
institutional websites, and open communications between researchers whether on community preprint
servers or preprint commenting platforms. Authors should disclose details of preprint posting, including
doi and licensing terms, upon submission of the manuscript in Biochemistry (Moscow) journal. Once the
preprint is published, it is the author’s responsibility to ensure that the preprint record is updated with a
publication reference, including the doi and a URL link to the published version of the article on the
journal website.
3.9. All physical values are recommended to be presented in the International System SI.
3.10. Physical and chemical symbols in the text, structural formulas of organic compounds, and
mathematical equations must be generated on a computer. In the designation with letters of relationships
of units a forward slash should be used, e.g., mol/s (mol per second). In the more complex expressions
alongside with the forward slash brackets are used to prevent an ambiguity: a/(bc), but not a/b/c or a/bc;
(a/b)c, but not a/b · c. The relationships can also be represented as the product of symbols of the units
raised to a degree (positive and negative), e.g., mol · s
1
. Expression type mA/gel, µmol/min · mg
protein, etc. are not allowed. In such cases it should be written as follows: mA per 1 column of gel,
μmol/min per 1 mg protein, etc.
3.11. In preparing the article it is necessary to take into account the rules for the use of symbols,
abbreviations, conventional designations, etc. recommended by the Biochemical Nomenclature
Committee of the International Union of Biochemistry and Molecular Biology (https://iubmb.org). The
conventional designations given in these Instructions are mandatory for the authors and may be applied
without special interpretation (definition). Symbols and abbreviations not specified in the list presented
below are to be defined on the first page, sub-line, under the heading “Abbreviations”.
It should be remembered that abbreviations create difficulties for the reader, therefore their use
should be restricted to a minimum. Clarity and lack of ambiguity are more important than conciseness. On
the other hand, it is sometimes convenient to use abbreviations for the names of substances and other
terms, particularly in equations, tables, and figures.
Names of simple substances may be replaced by their formulas, e.g., NaCl instead of
“sodium
chloride”, CH
3
COOH or AcOH instead of “acetic acid”. When abbreviations for
chemical compounds are
needed, maximum use should be made of standard chemical symbols (C, H, O, P, S, Na, Cl, etc.), trivial
names (folate, etc.) and symbols (Me, Pr, Ac for methyl, propyl, acetyl, respectively).
One-letter symbols are preferred over three-letter symbols for amino acid residues in polypeptides
and proteins:
Alanine
Ala
A
Arginine
Arg
R
Asparagine
Asn
N
Aspartic acid
Asp
D
Aspartic acid or asparagine
Asx
B
Cysteine
Cys
C
Glutamine
Gln
Q
Glutamic acid
Glu
E
Glutamic acid or glutamate
Glx
Z
Glycine
Gly
G
Histidine
His
H
Isoleucine
Ile
I
Leucine
Leu
L
Lysine
Lys
K
Methionine
Met
M
Phenylalanine
Phe
F
Proline
Pro
P
Serine
Ser
S
Threonine
Thr
T
Tryptophan
Trp
W
Tyrosine
Tyr
Y
Valine
Val
V
Macromolecular compounds of repeated units may be represented by the prefix “poly” or
the
subscript n. Thus, polylysine can be referred to as poly(Lys) or (Lys)
n
; a polymer of alternating alanine
and lysine residues is poly(AlaLys) or (AlaLys)
n
; similar polymer with random distribution of alanine
and lysine residues is poly(Ala, Lys) or (Ala, Lys)
n
. The index n may be replaced by the average number,
e.g. (Lys)
10
or with indicating the range, e.g., (Lys)
8-12
.
For the three-letter designation of amino acid residues of proteins direct letters should be used, of
which the first letter is capital and the rest ones are lower-case. Amino acid residues with the number in
the sequence should be given as Asn223.
According to the genetic nomenclature rules, gene names should preferably represented by
three-letter designation in Latin Italic letters (except drosophila and some other organisms). The
corresponding products (proteins) should be designated with capital letters. In prokaryotes normal genes
are designated with lower-case letters with the “plus” symbol in superscript (e.g., proA

); mutant genes are
also designated with lower-case letters with a mutation number (e.g., proA22). In eukaryotes normal
genes are designated with capital letters (e.g., LEU2) and mutant genes with lower-case letters with a
mutation number, if necessary (e.g., leu2-3).
When a new gene sequence is described in the article, it is necessary to pre-deposit it to the
GenBank database or to another publicly available database.

3.12. Nomenclature of isotope-labeled compounds. The isotope symbol is placed in square brackets
directly attached to the front of the atom name (without a space): [
14
C]urea, [
14
C]leucine, L-
[methyl
14
C]methionine. When more than one position in a substance is labeled and the positions of these
atoms are not indicated, the number of labeled atoms is indicated by
the subscript index to the right of the
symbol: [
14
C
2
]glycol acid. The symbol “U” indicates
uniform distribution of the label: the designation [U-
14
C]glucose means that the
14
C isotope is distributed equally between all six positions. The symbol “G”
indicates general labeling (in [G-
14
C]glucose
14
C may be present at any, but not necessary all, of the six
positions). In the latter case [
14
C]glucose will suffice.
The isotope prefix precedes the part of the compound name to which it refers:
iodo[
14
C]acidic acid,
1-amino-[
14
C]methylcyclopentanol (H
2
N
14
CH
2
C
5
H
8
OH), fructose-1,5-[1-
32
P]biphosphate. Terms such as
[
131
I]-labeled albumin should not be abbreviated to [
131
I]albumin, since native albumin does not contain
iodine; the designation [
131
I]iodoalbumin is permitted.
When a compound contains isotopes of more than one element, their symbols should be placed in
alphabetical order: [3-
14
C, 2,3-D
15
N]serine. Deuterium can be designated with the symbols
2
H or D and
tritium with
3
H or T.
The positions of isotope labeling are indicated by Arabic numerals, Greek letters, or prefixes
placed within the square brackets before the element symbol to which they are attached by a hyphen: [1-
3
H]ethanol, L-[-
14
C]leucine, [carboxy-
14
C]leucine, [3,4-
14
C,
35
S]methionine, L-[methyl-
14
C]methionine.
The above rules are also applied when the labeled compounds are designated by the standard
abbreviations or symbols: [-
32
P]ATP, [
32
P]CMP (not CM
32
P). However, radioactive inorganic
phosphate
and pyrophosphate may be designated
32
P
i
and
32
PP
i
, respectively.
Square brackets may be omitted for the simple molecules by writing their chemical formulas:
14
CO
2
, H
2
18
O, D
2
O, H
2
35
SO
4
,
32

3
(but [
32
P]phosphate). Square brackets are not to be used
when the
isotope symbol is attached to a word which is not a chemical name or refers to a class name of compounds:
131
I-labeled,
3
H-ligands,
14
C-steroids,
14
C-amino acids.
When describing results of experiments with labeled compounds, absolute values of radioactivity
should be given, wherever possible, in curies (Ci), becquerels (Bq), disintegrations per minute (DPM), or
counts per minute (CPM).
3.13. Recommendations on specific topics common for biochemical literature are given below [see also
Biochem. J., 289, 1-15 (1993)].
Animals, plants, microorganisms. The full binomial names should be included for all
experimental animals (other than common laboratory animals) and plants. The strain, variety, and, if
possible, source of the material should be given. Reports describing effects of changes in feeding should
contain composition of the feeding mixtures (growing media).
For microorganisms, full binomial Latin names should be printed italicized in the title, abstract,
and at the first mention in the text. Further in the text, single-letter abbreviation may be given for the
generic name along with the full species name. The number of the organism in the collection from which
it was obtained should be given. If two genera with the same initial letter are studied, abbreviations such
as Strep. and Staph. may be used. Ranks higher than genus (e.g., Eubacteria, Lactic acid bacteria) generic
names used adjectively (e.g., staphylococcal) are not italicized.
Centrifugation. When conditions for centrifugation are critical, sufficient information should be
provided for the experiment to be repeated: the centrifuge rotor, the quantitative composition of the
suspension medium, operation temperature, the time of rotor operation at constant velocity (ignoring
acceleration and deceleration periods), the centrifugal field based on the average radius of the liquid
rotation. For example: “The centrifugation was performed for 15 min at 2°C and 10,000g
(r
av.
8 cm)”.
For density-gradient centrifugation, the centrifuge and rotor manufacturer(s), temperature, and
gradient composition should be stated. Results should preferably be presented as a function of distance
from the rotor center rather than the fraction number; in this case it is unnecessary to indicate top and
bottom of the gradient. If fraction numbers are used, the top and bottom of the gradient should be
indicated.
For ultracentrifugation, the following parameters are used: sedimentation coefficient (not
constant), s; sedimentation coefficient at zero concentration at 20°С in water, s
0
20,w
; Svedberg unit (10
13
s), S;
particle specific volume, v; diffusion coefficient, D; diffusion coefficient in
water at 20°С, D
0
20,w
.
The temperature at which the sedimentation and diffusion were performed
should be indicated.
Chromatography. Using photographs or schemes of paper and thin-layer chromatography should
be restricted to cases when it is difficult to give corresponding information in the text. The rate of a
substance movement relatively to the solvent front in paper
or thin-layer chromatography is characterized
by R
f
value. The solvent composition is best described as follows: butan-1-ol : CH
3
COOH : H
2
O
(4 : 4 : 1, v/v).
Elution diagrams for column chromatography should be shown with the effluent volume increasing
from left to right. Units of concentration and volume should be indicated clearly.
Column dimensions and, if possible, column void volume (V
0
) should also be stated. The elution peak
maximum may be characterized by elution volume (V
e
) or, preferably, by partition coefficient ( or K
D
).
Calibration curves for columns (e.g., plots of molecular mass versus V
e
or K
D
) will not be published.
Electrophoresis. Photographs of gel electropherograms will be published, if they provide some
important information; drawings or densitograms may be more informative in certain cases. Composition
of the electrophoretic medium, pH, temperature, electrophoretic mobilities (m), and operative voltage
should be presented in the text. The symbol pI should be used for isoelectric points.
Enzymes. For nomenclature the authors should follow recommendations of the latest edition of
“Enzyme Nomenclature” (1992, Academic Press, New York) with the supplements (http://www.enzyme-
database.org/news.php) taken into account. When a particular enzyme is mentioned in the text of
manuscript, its EC (Enzyme Commission) number should be provided alongside. Units of enzyme amount
should be defined in each paper in terms of the rate of the reaction catalyzed under specified conditions.
The SI unit for the rate is 1 mol of the substrate transformed per second (or 1 mol of the product formed
per second). This value of the rate gives the unit of the enzyme amount called “katal” (symbol: kat). Units
of enzyme activity may be also expressed in terms of its amount that provides another rate of the reaction,
e.g., 1 µmol substrate transformed per minute.
Concentrations of proteins are often determined versus a standard protein (e.g., BSA) solution; the
standard protein used, its source, and, if possible, water constant should be stated.
Rate constants for the forward and reverse reactions in the multistep enzyme-
catalyzed process
should be designated by k
+n
and k
n
, respectively. The Michaelis constant (K
m
) is defined as substrate
concentration ([S]) which corresponds to v = V/2, where V (or V
max
)
is the
reaction rate under conditions of
the enzyme saturation with the substrate and v is the rate of product appearance or substrate disappearance.
For reactions involving two substrates (A and B) K
A
= [A] at v = V/2 and [B] extrapolated to infinity; the
value of [A] at which v = V/2 at the final concentration (which should be specified) of B should be referred
to as an apparent
Michaelis constant for A (
K
A
m,app
). Other parameters used in enzyme kinetics include:
K
s
, dissociation constant for enzymesubstrate complex; K
i
, dissociation constant for enzymeinhibitor
complex; [I]
50
, inhibitor concentration at which the rate is decreased by half; h, Hill
coefficient (parameter
in the Hill equation used to describe S-shaped dependences of v on the substrate or inhibitor
concentrations) [see also “Recommendations on Symbolism and Terminology in Enzyme Kinetics”
published in Arch. Biochem. Biophys., 224, 732-740 (1983)].
Substance amount, molecular mass, Dalton, and molar concentration. The SI unit of the
substance amount (n) is mole (abbreviated mol), i.e., the substance amount containing the same number of
structural units (molecules, atoms, ions, electrons, etc.) as the number of carbon
atoms in 0.012 kg of
12
C
(the Avogadro’s constant, N
A
= 6.02·10
23
per mol, gives the number of
structural units in the mole of any
substance). Molar mass (M) is the mass of 1 mol of the substance (m/n), and its dimension is g/mol or
kg/mol. Obviously, mass (m, g), amount (n, mol), and molar mass (M, g/mol) are different terms which are
related to one another with the relationship m = nM. There are two preferred ways of specifying the mass
of a biochemical
entity: relative molecular mass (M
r
, formerly “molecular weight”) is the ratio of the
molecule
mass to 1/12 of the atom
12
C atom. Hence, it is dimensionless. Molecular mass is the mass of
one molecule of a substance expressed in Daltons; the Dalton is defined as 1/12 of the
12
C atom,
or M/N
A
.
Thus, it may be said that a protein has a relative molecular mass of 50,000 (M
r
=
50,000) or a molecular
mass of 50,000 Daltons (better, 50 kDa), and may be referred to as the
50,000-M
r
protein or the 50-kDa
protein. It is not correct to express M
r
in Daltons, either M
r
or
molecular mass (kDa) should be used
throughout the paper.
Solutions should be described in terms of molarity (M, mM, µM, etc.), i.e., the number of the
substance moles in 1 liter of the solution, not normality (N). The decimal system should be used,
e.g., 0.25 M HCl. Concentration expressed in % must be defined as w/w, w/v, or v/v, e.g., 5% (w/v) means
5 g/100 ml. For salts solutions with concentration expressed in %, it should be indicated whether the
compounds were hydrated or anhydrous.
Nucleotide sequences. Authors should remember that nucleotide sequence should be determined
in both DNA chains. A clear description of such determinations and data on the complete sequence will
suffice.
Metric prefixes in tables and figures. Authors must be careful when using exponents to avoid
numbers with too many digits in the headings of tables and in figures. This is illustrated by the following
examples: 1) a concentration 0.00015 M may be expressed as 15·10
5
M, but it is preferable to give it
using a prefix, as 0.15 mM or 150 µM; it is appropriate to express concentration of 0.15 in the table or
figure under the heading “Concentration, mM” or 150 under “Concentration, µM”, or 15 under
“Concentration × 10
5
, M” (but not 15 under the heading “Concentration, M × 10
5
”); 2) listing of 2 under
the heading “10
3
k” means k = 0.002, and 2 under the heading “10
3
k” means k = 2000; 3) complex
quantities are treated similarly; a value of 200 M
1
for 1/[S] would appear as “2” under the heading “10
2
/[S], M
1
” or as “0.2” under the heading “1/[S], mM
1
”. Concentrations may conveniently be indicated by
square brackets.
The following decimal prefixes and their symbols should be used for multiples and subdivisions of
units:

* To be avoided whenever possible (except for cm).
A combination of a prefix and a unit is treated as one symbol and may be raised to a power without
using brackets, e.g., mM
1
and cm
2
.
Buffer solutions must be specified in a way allowing readers to reproduce the experimental
conditions. It is useful to give complete composition of each buffer solution in the
“Materials and
Methods” section or at the first mention, e.g., 0.09 M CH
3
COONa/0.01 M CH
3
COOH, pH 5.6 (that means
that the buffer solution has these concentrations of these
substances). A short designation “0.1 M sodium
acetate buffer, pH 5.6” may be used thereafter throughout the paper. If a buffer contains two or more
ionizable substances, e.g., pyridine and
CH
3
COOH, concentration of each component must be specified.
Trivial names of the following common buffers may be used without definition:
Aces
2-[(Amino-2-oxoethyl)amino]ethanesulfonic acid
Ada
(N-[2-Acetamido]-2-iminodiacetic acid
Bes
2-[Bis(2-hydroxyethyl)amino]ethanesulfonic acid

Tris
2-Amino-2-(hydroxymethyl)-1,3-propanediol
Incubation media such as Krebs–Ringer solution, Eagle’s medium, or Waymouth’s medium should
be defined by citing the reference or by giving their compositions.
Spectra and spectroscopy data. Full spectra should be published only if they demonstrate novel
or important information. The spectra for UV or visible absorption, fluorescence, circular dichroism, and
optical rotatory dispersion should have a wavelength scale (nm or µm). Where possible, molar terms
should be used when describing absorption, optical rotation, and circular dichroism. As stated above,
commonly used abbreviations of methods (ORD, CD, EPR, ESR, and NMR) do not need definition.
Visible and ultraviolet absorption spectroscopy. The value of log(I
0
/I) characterizes
optical
density of a solution, and this represents absorbance when scattering and reflection are negligible. If
scattering is taken into account, e.g., when density of a cell culture is estimated, the more general term
transmittance (T) should be used. Otherwise, the term absorbance should be used, but not extinction or
optical density. The symbols used are as follows: A, absorbance
(log (I/I
0
)); a, specific absorption
coefficient (liter · g
1
· cm
1
, or alternatively used A
1%
cm
); ε,
molar absorption coefficient (absorbance of
1 M solution in 1 cm light-path) (liter · mol
1
· cm
1
, or M
1
· cm
1
, but not cm
2
· mol
1
). Wavelength (nm)
at which measurements were done are
given without units: A
280
. No equal sign is placed between ε or A
and its numerical value.
IR-spectra are reported as percentage of transmittance (T) versus wavelength (µm) or
frequency (cm
1
).
Optical rotation is reported as specific rotation ([]
λ
t
), which is numerically equal to
the rotation
(in degrees) in a solution with concentration of 1 g/ml and a 1 dm (10 cm) light-path at wavelength λ and
temperature t. The solution concentration (g/100 ml) and solvent should be
stated, e.g., []
420
27.5° (2 g
per 100 ml methanol). Data may be also presented as molar rotation:
[M] = [] · M
r
and [m] = [] · M
r
/100.
For biopolymers, optical rotatory dispersion ([m]
m.r.w.
)
is reported for the mean residue ([m]
m.r.w.
;
the dimension of [m] is deg · cm
2
· dmol
1
.
Optical rotatory dispersion is reported as variation of [
] or [m] with changing of wavelength or
frequency.
Circular dichroism is reported as the molar absorption coefficient (∆ε = ε
L
ε
R
, where ε
L
and ε
R
are absorption coefficients for the light polarized to the left and to the right) or as molar ellipticity [θ]
M
.
For biopolymers, molar concentrations in terms of the mean residue M
r
are often
used. Units of molar
absorption coefficient are liter/mol per 1 cm or M
1
· cm
1
; units of molar ellipticity are the same as for
optical rotation [m] calculated per the mean residue. The
relationship between ∆ε and [θ]
M
= 3300 · ε
Fluorescence spectroscopy. In describing fluorescence (F) excitation and emission spectra, it
should be stated whether they are relative, normalized or corrected, and what is the correction nature. Data
of the fluorescence polarization and spectra are reported as polarization ratio (P) or anisotropy ratio (A);
both values are dimensionless.
Statistical treatment of results. Data from a large number of independent experiments should be
reported in a way permitting evaluation of their reproducibility and significance. When the purpose is to
determine quantitative or statistical characteristics of a population, the basic information is adequately
given by: 1) the number of independent experiments (repeated measurements in one animal, results from
pooled tissues, etc. represent only one independent estimate); 2) the mean value; 3) the standard deviation;
the coefficient of variation of the standard error of the mean value estimation. It should be clearly
indicated whether the standard deviation or the standard error was used. A convenient form for including
these data into a table is, for example, 263 ± 2.5 (10), where the number in parentheses represents the
number of values used in calculating the mean.
If the results are claimed significant, a significance test should be performed, and probability
estimated. Normal distribution statistics is used unless otherwise is stated.
It is recommended to provide data that are impossible or impractical to include in the printed
journal (such as large data sets of identified proteins in proteomic research) as supplements, which will be
available to readers only on-line, at the journal website. Such supplements should be referred to in the
manuscript at the appropriate place in the text.
4. Processing of Manuscripts (Reviewing, Editing, Proofs)
4.1. Submission. A correctly submitted manuscript received by the Staff Editor is assigned a registration
number and the date of receipt is recorded, and the authors are informed by e-mail about it by the Editors
(or the ID number is created by the Pleiades Portal automatically). Manuscripts not written according to
the rules are returned to the authors without reviewing.
4.2. Reviewing. When submitting a manuscript, authors may indicate two-three potential reviewers
(name, e-mail address) from experts in the field of research, as well as those whose participation in the
reviewing is undesirable.
All manuscripts are reviewed by the Executive Editor-in-Chief and sent to the Handling Editor
knowledgeable in the relevant specific field of study; Handling Editor, in turn, indicates two or three
specialists to review the manuscript. The list of Handling Editors and members of the Editorial Board is
posted on the journal’s website, as well as on the Biochemistry (Moscow) sites on the Pleiades and
Springer portals.
Based on the expert opinions, the Editorial Board determines the further fate of the manuscript and
in controversial cases attracts additional reviewers. By decision of the Editorial Board, the manuscript may
be accepted for publication in the presented form, sent to the authors for major/minor revision, or rejected.
A manuscript may be rejected because of insufficiently high evaluations by the reviewers, because of
inconsistency with the profile or level of the journal publications.
A manuscript which received the highest score from two independent reviewers is published as
Accelerated publication” (publication time 1 month).
If necessary, the manuscript is sent to the authors for revision according to the comments of the
reviewers and editors, after which it is re-reviewed, and the Editorial Board again decides on acceptability
of the manuscript for publication. At the beginning of the published article, the dates are given of the
initial receipt of the manuscript, the receipt after the revision, and of the acceptance for publication.
The revised manuscript should be returned to the Editor within two months after the authors
receiving the reviews.
The practice of “single-blind review” is accepted in the journal, i.e., the names of reviewers are
unavailable to authors, and confidentiality of the reviewers is strictly observed. All editorial letters to the
authors are signed by the responsible Executive Secretary of the journal.
4.3. Communication. At all stages of working with manuscripts, as well as for communication with the
authors, the Editorial Board uses e-mail or Pleiades Publishing Portal, therefore, the authors should be
very attentive to the e-mail address specified in the manuscript and should promptly report any changes
occurred.
4.4. Translation. Each issue of the journal is prepared simultaneously in Russian and English. Articles are
translated by a group of highly qualified translators specialized in biochemistry. During the work, the
editors and translators often need to contact the authors and eliminate inaccuracies in the text of the article.
Corrections agreed with the authors are introduced in both the Russian and English texts at the editing
stage.
4.5. Editing. All the articles are edited by the Scientific Editors of the journal, and the prepared text is sent
to the authors for correction.
4.6. Proofreading. The Editorial office sends to the authors the proofreading of the article as a pdf-file
and instructions for correcting it by e-mail. At the proofreading stage, no replacement of text, figures or
tables is allowed. If, nevertheless, it is necessary, the problem is resolved by the Editorial Board; in
exceptional cases, the article is transferred to another issue of the journal.
4.7. Online First mode. Papers accepted after accelerated editorial process can be published as Online
first on the Springer website (https://link.springer.com/journal/10541).
4.8. Upon the publication, the Editor sends pdf-file of the article to the authors.
