Constitutive activation of the Escherichia coli Pho regulon upregulates rpoS translation in an Hfq-dependent fashion.

Journal of bacteriology - 1 Oct 2003

Ruiz Natividad, Silhavy Thomas J

Abstract excerpt

Regulation of the sigma factor RpoS occurs at the levels of transcription, translation, and protein stability activity, and it determines whether Escherichia coli turns on or off the stationary-phase response. To better understand the regulation of RpoS, we conducted genetic screens and found that mutations in the pst locus cause accumulation of RpoS during exponential growth. The pst locus encodes for the...
