The cell wall of Actinoplanes brasiliensis INA 3802 contains a teichuronic acid of unusual structure, as determined in a nondestructive way by 1H- and 13C-NMR spectroscopy. The polysaccharide comprises six tetrasaccharide units of the following composition: -->6)-alpha-D-Glcp-(1-->4)-beta-D-2,3-diacetamido- 2,3-dideoxyGlcpA-(1-->4)-alpha-D-2,3-diacetamido-2,3-dide oxyGlcp-(1-->4)-beta- D-2,3-diacetamido-2,3-dideoxyManpA. A polymer of such structure has not heretofore been reported for procaryotic cell walls.
通过¹H-和¹³C-核磁共振光谱以非破坏性方式测定,巴西游动放线菌INA 3802的细胞壁含有一种结构异常的磷壁酸。该多糖由六个具有以下组成的四糖单元组成:→6)-α-D-葡萄糖-(1→4)-β-D-2,3-二乙酰氨基-2,3-二脱氧葡萄糖醛酸-(1→4)-α-D-2,3-二乙酰氨基-2,3-二脱氧葡萄糖-(1→4)-β-D-2,3-二乙酰氨基-2,3-二脱氧甘露糖醛酸。迄今为止,尚未有关于原核细胞壁具有这种结构聚合物的报道。
