Peptidoglycan from Deinococcus radiodurans was analyzed by high-performance liquid chromatography and mass spectrometry. The monomeric subunit was: N-acetylglucosamine-N-acetylmuramic acid-L-Ala-D-Glu-(gamma)-L-Orn-[(delta)Gly-Gly]-D-Ala-D-Ala. Cross-linkage was mediated by (Gly)2 bridges, and glycan strands were terminated in (1-->6)anhydro-muramic acid residues. Structural relations with the phylogenetically close Thermus thermophilus are discussed.
通过高效液相色谱和质谱分析法对耐辐射球菌的肽聚糖进行了分析。其单体亚基为:N-乙酰葡糖胺-N-乙酰胞壁酸-L-丙氨酸-D-谷氨酸-γ-L-鸟氨酸-[(δ)甘氨酰-甘氨酸]-D-丙氨酸-D-丙氨酸。交联由(Gly)2桥介导,聚糖链以(1→6)脱水胞壁酸残基结尾。文中讨论了与亲缘关系较近的嗜热栖热菌的结构关系。
