Flagella is the motile organ of bacteria, and bacteria are driven by the flagella to move toward the best niche that is beneficial to their survival. The rotary direction of flagella is controlled by the flagellar motor. Chemotactic two-component system is an important link between the external signal stimulation and bacterial flagellar movement. The rotor of the flagellar motor is at the output of the bacterial chemotaxis pathway. Both of them contribute to the formation of biofilm, quorum sensing, stress response, and bacterial virulence. Based on their close relationship and important physiological roles and, the advances of the effect of chemotactic two-component system and flagella-related proteins were reviewed in this paper

鞭毛是细菌的运动器官,细菌在鞭毛的驱动下向利于自身生存的环境运动。 鞭毛马达控制鞭毛的旋转方 向,进而控制细菌的运动方向。 双组分系统是联系外界信号刺激与细菌鞭毛运动的重要枢纽。 鞭毛马达中的转子位 于细菌趋化双组分系统的信号末端,二者在生物膜形成、群感效应、压力响应和细菌毒力等功能上紧密相连。 基于此, 本文对双组分系统和鞭毛相关蛋白的研究现状进行了综述。
