来自藤黄微球菌的肽聚糖

应用

肽聚糖是细菌细胞壁，尤其是革兰氏阳性细菌的主要成分。肽聚糖由β-(1,4)连接的N-乙酰氨基葡糖和N-乙酰氨基甲酸的交替残基，以及形成交联，以形成网状结构的肽链组成。可以比较来自不同细菌物种的肽聚糖，以确定结构和组成的差异/变异和系统发育进化。可使用来自不同物种的肽聚糖来区分和表征肽聚糖水解酶。

Description

Peptidoglycans are major components of bacterial cell walls, especially of gram-positve bacteria. Peptidoglycan are composed of alternating residues of β-(1,4) linked N-acetylglucosamine and N-acetylmuramic acid and peptide chains that create cross-linkage to create mesh structures. Peptidoglycans from different bacterial species can be compared to determine structural and compositional differences/variations and phylogenetic evolution. Peptidoglycans from different species may be used to differentiate and characterize peptidoglycan hydrolases.
