The cell wall of Actinoplanes lobatus VKM Ac-676(T) (family Micromonosporaceae; order Actinomycetales; class Actinobacteria) contains two anionic glycopolymers. The major one is a teichuronic acid with a linear structure of the chain and heterogeneous repeating units, consisting of glucopyranose residues and statistically alternating residues of diaminouronic acids having the d-manno,l-gulo and d-gluco configurations in a ratio of 6:3:1, respectively. The teichuronic acid of this structure has not hitherto been found in Gram-positive bacteria. The minor glycopolymer is a teichoic acid of poly(glycosylpolyol phosphate) nature with the repeating unit -6)-[α-d-Manp(1→4)]-β-d-Galp-(1→2)-snGro-(3-P-. The structures of the glycopolymers were established by chemical methods and NMR spectroscopy.
游动放线菌 VKM Ac-676(T)（微单胞菌科；放线菌目；放线菌纲）的细胞壁含有两种阴离子糖聚合物。主要的是一种线性结构的海藻糖醛酸链，其重复单元具有不均一性，由葡萄糖醛酸残基和统计交替的二氨基糖醛酸残基组成，分别具有 d-甘露糖、l-古洛糖和 d-葡萄糖构型，比例为 6:3:1。这种结构的海藻糖醛酸迄今尚未在革兰氏阳性菌中发现。次要的糖聚合物是聚（糖基多元醇磷酸盐）性质的磷壁酸，其重复单元为 -6)-[α-d-Manp(1→4)]-β-d-Galp-(1→2)-snGro-(3-P-。糖聚合物的结构是通过化学方法和 NMR 光谱确定的。
