Abstract excerpt
Transcription of the gene osmE of Escherichia coli is inducible by elevated osmotic pressure and during the decelerating phase of growth. osmE expression is directed by a single promoter, osmEp. Decelerating phase induction of osmEp is dependent on the sigmas (RpoS) factor, whereas its osmotic induction is independent of sigmas. Purified Esigmas and Esigma70 were both able to transcribe osmEp in vitro on...
