Role of activator site position and a distal UP-element half-site for sigma factor selectivity at a CRP/H-NS-activated sigma(s)-dependent promoter in Escherichia coli

Transcription initiation by the stress-associated sigma(S)-containing RNA polymerase holoenzyme (E sigma(S)) in Escherichia coli is often subject to complex regulation that involves multiple additional regulators and histone-like proteins. csiD is a stationary phase-inducible sigma(S)-dependent gene...
