摘要

Ⅶ型分泌系统(Type VII secretion system, T7SS)是唯一一种仅存在于革兰氏阳性细菌中的分泌系统。T7SS在细菌与细菌、细菌与宿主、细菌与环境相互作用中发挥着重要功能,与细菌的生长和致病性密切相关。T7SS的功能多样性与其所分泌的效应蛋白的多样性密切相关。因此,本文将围绕T7SS所分泌的效应蛋白展开讨论,对效应蛋白的结构和功能、分泌机制及其基因转录水平的调控方式等多方面进行综述,以期为进一步研究细菌的T7SS提供新的思路。

Abstract

The Type VII secretion system (T7SS) is the only secretion system exclusively found in Gram-positive bacteria. It closely links to bacterial growth and virulence, which plays an important role in the interaction between bacteria-bacteria, bacteria-host, and bacteria-environment. Overall, the functional diversity of T7SS is associated with its effector proteins. Therefore, the article will discuss the effector proteins secreted by T7SS, providing a comprehensive review of their structure and function, secretion mechanisms, and the regulatory modes of gene transcription, with the aim to offer new perspectives for further research into bacterial T7SS.
