Arabinogalactan proteins (AGPs) are complex plant proteoglycans that function as dietary fiber utilized by human intestinal bacteria such as Bifidobacterium and Bacteroides species. However, the degradative mechanism is unknown because of the complexity of sugar chains of AGPs as well as variation among plant species and organs. Recently, AGP degradative enzymes have been characterized in Bifidobacterium and Bacteroides species. In this review, we summarize the characteristics and functions of AGP degradative enzymes in human intestinal bacteria.
阿拉伯半乳聚糖蛋白 (AGP) 是一种复杂的植物蛋白聚糖，作为膳食纤维被人类肠道细菌如双歧杆菌和拟杆菌属物种所利用。然而，由于 AGP 糖链的复杂性以及植物物种和器官之间的差异，其降解机制尚不清楚。最近，双歧杆菌和拟杆菌属物种中的 AGP 降解酶的特性已被阐明。在这篇综述中，我们总结了人类肠道细菌中 AGP 降解酶的特性和功能。
