Probing DNA Binding, DNA Opening and Assembly of a Downstream Clamp/Jaw in E. coli RNA Polymerase – λP(R) Promoter Complexes Using Salt and the Physiological Anion Glutamate

Transcription by all RNA polymerases (RNAP) requires a series of large-scale conformational changes to form the transcriptionally-competent open complex RP(o). At the λP(R) promoter, E. coli σ(70) RNAP first forms a wrapped, closed 100 bp complex I(1). The subsequent step opens the entire 13 base DN...
