What is 'CheA and CheW'?

Could somebody please explain? — Preceding unsigned comment added by 2A02:810D:AF3F:EC88:516A:E67:44B8:6D37 (talk) 10:48, 7 January 2017 (UTC)[reply]

In general these are chemotaxis-related proteins that may be coupled to a MCP (but I have also read that at the least one of the Che is mobile; there are images where they can be found at different parts of the bacterial cell). From memory, the list goes Che-W-A-Y, which is how I remember it ("way"); I typically forget the role of CheW, but CheA phosphorylates CheY, and when CheY is phosphorylated it is active to cause a CCW orientation of the flagellar motor, causing the bacterium to tumble. I have omitted lots of information here but this is in general what most text-books note down about the role. Which makes sense - bacteria only have to tumble when they do not move towards a stronger gradient of nutrients after all. 2A02:8388:1604:CA80:7AA0:255D:4602:ABA7 (talk) 17:35, 8 April 2019 (UTC)[reply]
