CheZ mutants with enhanced ability to dephosphorylate CheY, the response regulator in bacterial chemotaxis.

Biochimica et biophysica acta - 6 Oct 1993

Huang C, Stewart R C

Abstract excerpt

CheZ is a component of the chemotaxis signal-transduction pathway in Escherichia coli and Salmonella typhimurium. It is responsible for accelerating dephosphorylation of CheY and thereby antagonizing the tumble-promoting activity of CheY. In the absence of functional CheZ, cells are non-chemotactic and tumble constantly. We characterized the effects of two mutations in CheZ, R54C and V166G, that are unusual in...
