Mutations that alter the kinase and phosphatase activities of the two-component sensor EnvZ.

Journal of bacteriology - 1 Sept 1998

Hsing W, Russo F D, Bernd K K, Silhavy T J

Abstract excerpt

EnvZ, a membrane receptor kinase-phosphatase, modulates porin expression in Escherichia coli in response to medium osmolarity. It shares its basic scheme of signal transduction with many other sensor-kinases, passing information from the amino-terminal, periplasmic, sensory domain via the transmembrane helices to the carboxy-terminal, cytoplasmic, catalytic domain. The native receptor can exist in two active but...
