Promoter opening by σ(54) and σ(70) RNA polymerases: σ factor-directed alterations in the mechanism and tightness of control
Transcription control at the melting step is not yet understood. Here, band shift, cross-linking, and transcription experiments on diverse DNA probes were used with two bacterial RNA polymerase holoenzymes that differ in how they regulate melting. Data indicated that both σ(54) and σ(70) holoenzymes...
