周质结合蛋白依赖的转运系统研究进展

Advance in Periplasmic Binding Protein-Dependent Transport System

周质结合蛋白依赖的转运系统是复杂的、多组分的透酶系统,具有广泛的生理功能。在从微生物到人类的所有物种中都可发现这种转运系统或与之相关的结构。本文以细菌为例描述了这类系统的基本结构和功能以及转运机制。

Periplasmic binding protein(PBP)-dependent transport system is a complex, multicomponent permeases system with a diversity of physiological functions. The system or the related structure exists in all species from microbes to human beings. In this review, bacteria were taken as examples to illuminate the structure, function and transport mechanism of this transport system.
