Proteins containing the NIF3 domain are highly conserved and are found in bacteria, eukaryotes, and archaea. YbgI is an Escherichia coli protein whose gene is conserved among bacteria. The structure of YbgI is known; however, the function of this protein in cells remains obscure. Our studies of E. coli cells with deleted ybgI gene suggest that YbgI is involved in formation of the bacterial cell wall.
