Negative regulation by RpoS: a case of sigma factor competition.

Molecular microbiology - 1 Aug 1998

Farewell A, Kvint K, Nyström T

Abstract excerpt

A mutation in the Escherichia coli gene encoding the stationary phase-inducible sigma factor (sigmaS, RpoS) not only abolishes transcription of some genes in stationary phase, but also causes superinduction of other stationary phase-induced genes. We have examined this phenomenon of repression by...
