The structures of teichoic acids of three Nocardiopsis species were established. The cell wall of Nocardiopsis listeri VKM Ac-1881T contains two teichoic acids (TA). TA1 is 1,3-poly(glycerol phosphate) with 50% glycerol phosphate residues substituted by alpha-N-acetylglucosamine in the C-2 position. TA2 is 1,5-poly(ribitol phosphate) with each ribitol phosphate unit carrying pyruvate acetal groups in the 2 and 4 positions. The cell wall of Nocardiopsis lucentensis VKM Ac-1963T contains only one teichoic acid of the same structure as TA1 of N. listeri. The teichoic acid of the Nocardiopsis tregalosei VKM Ac-942 is a 1,3-poly(glycerol phosphate) substituted (60%) by beta-glucopyranosyl residues. Structures of polymers were studied by chemical and NMR spectroscopy methods. The presented results confirm the species-specificity of teichoic acids from Nocardiopsis genus.
