Abstract
Bodhankar et al. reported a noncanonical sensing mechanism that involves signal interaction with the McpA chemoreceptor signaling domain resulting in a chemorepellence response of Bacillus subtilis. The identified repellent binding site is analogous to that for attractant binding in McpB, another B. subtilis chemoreceptor.
摘要
Bodhankar 等人报告了一种非经典的感应机制，该机制涉及与 McpA 化学感受受体信号结构域的信号相互作用，导致枯草芽孢杆菌的化学逃避反应。鉴定出的排斥结合位点类似于另一种枯草芽孢杆菌化学感受器 McpB 中吸引剂结合的位点。
