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.
发现绿色诺卡氏菌VKM Ac-1880T的细胞壁含有两种结构不同的磷壁酸：未取代的3,5-聚（核糖醇磷酸）和1,3-聚（甘油磷酸），在2位分别有10%被α-N-乙酰葡糖胺取代，5%被O-乙酰基取代。通过化学分析和核磁共振光谱研究了聚合物的结构。所得结果与16S rRNA序列数据相关性良好，并证实了诺卡氏菌属中磷壁酸的种特异性。
