Teichoic acids of the cell wall of Nocardiopsis listeri, Nocardiopsis lucentensis, and Nocardiopsis tregalosei.

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.
