Correlated switch binding and signaling in bacterial chemotaxis.

The Journal of biological chemistry - 30 Jun 2000

Schuster M, Zhao R, Bourret R B, Collins E J

Abstract excerpt

In Escherichia coli, swimming behavior is mediated by the phosphorylation state of the response regulator CheY. In its active, phosphorylated form, CheY exhibits enhanced binding to a switch component, FliM, at the flagellar motor, which induces a change from counterclockwise to clockwise flagellar rotation. When Ile(95) of CheY is replaced by a valine, increased clockwise rotation correlates with enhanced...
