Abstract:
The cell wall of Nocardiopsis prasina VKM Ac-1880T was found to contain two structurally different teichoic acids: unsubstituted 3,5-poly(ribitol phosphate) and 1,3-poly(glycerol phosphate), substituted at position 2 by 10% with alpha-N-acetylglucosamine and by 5% with O-acetyl groups. The structure of the polymers was studied by chemical analysis and NMR spectroscopy. The results obtained correlate well with 16S rRNA sequence data and confirm the species-specificity of teichoic acids in the genus Nocardiopsis.
