A teichoic acid from the cell walls of Nocardioides luteus VKM Ac-1246T, a validly described species of the Nocardioides genus, is a 1,5-poly(ribitol phosphate) completely substituted at C-4 by alpha-D-galactopyranosyl residues carrying a 4,6-pyruvate ketal group in R-configuration. The structure of the repeating unit of the polymer is as follows: [figure]. The chain consists of approximately 18 repeating units and six beta-D-galactofuranosyl residues linked in the oligomer by 1,6-glycosidic bonds. The oligomer probably terminates the growing end of the teichoic acid. The structure of the polymer was determined by chemical methods and NMR spectroscopy. This teichoic acid has not been described so far.
来自藤黄诺卡氏菌VKM Ac-1246T（诺卡氏菌属中一个已有效描述的物种）细胞壁的一种磷壁酸是一种1,5-聚（核糖醇磷酸），其C-4位完全被携带R构型4,6-丙酮酸缩酮基团的α-D-吡喃半乳糖基残基取代。该聚合物重复单元的结构如下：[图]。该链由大约18个重复单元和六个通过1,6-糖苷键连接在低聚物中的β-D-呋喃半乳糖基残基组成。该低聚物可能终止磷壁酸的生长末端。该聚合物的结构通过化学方法和核磁共振光谱法确定。到目前为止，这种磷壁酸尚未见报道。
