TEICHOIC-ACIDS OF THE CELL-WALL OF NOCARDIAPSIS-LISTERI, NOCARDIOPSIS-LUCENTENSIS, AND NOCARDIPOSIS-TREGALOSEI

The structures of teichoic acids of three Nocardiopsis species were es tablished. 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 ribi tol phosphate unit carrying pyruvate acetal groups in the 2 and 4 posi tions. The cell wall of Nocardiopsis lucentensis VKM Ac-1963T contains only one teichoic acid of the same structure as TA1 of N, listeri. Th e teichoic acid of the Nocardiopsis tregalosei VKM Ac-942 is a 1,3-pol y(glycerol phosphate) substituted (60%) by beta-glucopyranosyl residue s. Structures of polymers were studied by chemical and NMR spectroscop y methods. The presented results confirm the species-specificity of te ichoic acids from Nocardiopsis genus.
