摘要
肽聚糖 (PG)是细菌细胞壁成分 ,大部分革兰氏阳性菌及部分革兰氏阴性菌细胞壁都含有PG。PG具有多种生物学活性 ,在调节宿主免疫功能方面发挥着重要作用。本文综述了细菌细胞壁PG的结构与分类、分离纯化、生物合成、代谢过程、生物学功能、免疫作用机制及应用前景。
Peptidoglycans are constituents of bacterial cell walls. Peptidoglycan is present in most of the Gram-positive bacteria and some of the Gram-negative bacterial. It exhibited various biological activities in the host, especially in immunomodulating. This article summarized the structure, isolation and purification, biological (synthesis), metabolism, functional mechanism and application prospect of peptidoglycan.
