The transcription bubble of the RNA polymerase-promoter open complex exhibits conformational heterogeneity and millisecond-scale dynamics: implications for transcription start-site selection.
Bacterial transcription is initiated after RNA polymerase (RNAP) binds to promoter DNA, melts ~14 bp around the transcription start site and forms a single-stranded "transcription bubble" within a catalytically active RNAP-DNA open complex (RP(o)). There is significant flexibility in the t...
