Expression of Escherichia coli pyruvate oxidase (PoxB) depends on the sigma factor encoded by the rpoS(katF) gene.

Molecular microbiology - 1 Mar 1994

Chang Y Y, Wang A Y, Cronan J E

Abstract excerpt

The activity of Escherichia coli pyruvate oxidase (PoxB) was shown to be growth-phase dependent; the enzyme activity reaches a maximum at early stationary phase. We report that PoxB activity is dependent on a functional rpoS(katF) gene which encodes a sigma factor required to transcribe a number...
