摘要
肽聚糖是乳酸菌细胞壁的必需成分,它的化学结构较为保守固定,而其合成是一个涉及多步反应的复杂过程。乳酸菌肽聚糖具有多种生物学活性,比如免疫增强功能、抗感染、抗肿瘤及抗过敏等。本文对乳酸菌肽聚糖的组成结构和生物学活性进行了简要的介绍,重点综述了近年来乳酸菌肽聚糖代谢及其调控过程的研究进展,并指出了乳酸菌肽聚糖未来研究的方向。
Peptidoglycan is an essential component of the cell wall of lactic acid bacteria, its chemical structure is mainly conservative and constant, and its biosynthesis is a complex process involving multi-step reactions. Peptidoglycan of lactic acid bacteria exhibits various biological activities, such as immune-enhancing functions, anti-infection, anti-tumor, and anti-anaphylaxis. In this review, the composition, structure and biological activity of peptidoglycan of lactic acid bacteria are outlined, the research development in metabolism and regulation of peptidoglycan is reviewed emphatically, and the direction to the future study of lactic acid bacteria peptidoglycan is proposed as well.
