Role of the periplasmic domain of the Escherichia coli NarX sensor-transmitter protein in nitrate-dependent signal transduction and gene regulation.

Molecular microbiology - 1 Sept 1996

Cavicchioli R, Chiang R C, Kalman L V, Gunsalus R P

Abstract excerpt

The narX, narQ and narL genes of Escherichia coli encode a nitrate-responsive two-component regulatory system that controls the expression of many anaerobic electron-transport- and fermentation-related genes. When nitrate is present, the NarX and NarQ sensor-transmitter proteins function to activ...
