The cell-wall teichoic acids of Nocardiopsis dassonvillei IMRU 509T, IMRU 504 and IMRU 1250 and Nocardiopsis antarcticus VKM Ac-836T have the same unique structure that has not heretofore been found in bacteria. The polymer is built of 10 to 13 repeating units: -1snGro3-P-3-beta-D-GalNAc1-2snGro3-P-. The structure has been established by chemical analysis and with NMR spectroscopy. A study of the cell-wall monosaccharide composition, peptidoglycan, and cell phospholipids also provides evidence for the close similarity of these two species.
达松维尔诺卡氏菌IMRU 509T、IMRU 504和IMRU 1250以及南极诺卡氏菌VKM Ac-836T的细胞壁磷壁酸具有相同的独特结构，这种结构迄今尚未在细菌中发现。该聚合物由10至13个重复单元组成：-1snGro3-P-3-β-D-GalNAc1-2snGro3-P-。该结构已通过化学分析和核磁共振光谱确定。对细胞壁单糖组成、肽聚糖和细胞磷脂的研究也为这两个物种的密切相似性提供了证据。
