Interactions between the 2.4 and 4.2 regions of sigmaS, the stress-specific sigma factor of Escherichia coli, and the -10 and -35 promoter elements.

Nucleic acids research - 1 Jan 2004

Abstract excerpt

The sigmas subunit of Escherichia coli RNA polymerase holoenzyme (EsigmaS) is a key factor of gene expression upon entry into stationary phase and in stressful conditions. The selectivity of promoter recognition by EsigmaS and the housekeeping Esigma70 is as yet not clearly understood. We used a...
