RpoS: Environmental signal to activation: regulation of RpoS, The RpoS regulon & Overview

The gene rpoS (RNA polymerase, sigma S, also called katF) encodes the sigma factor sigma-38 (σ38, or RpoS), a 37.8 kD protein in Escherichia coli. Sigma factors are proteins that regulate transcription in bacteria. Sigma factors can be activated in response to different environmental conditions. rpoS is transcribed in late exponential phase, and RpoS is…
