The expression of most bacterial genes commences with the binding of RNA polymerase (RNAP)–s70
holoenzyme to the promoter DNA. This initial RNAP–promoter closed complex undergoes a series of
conformational changes, including the formation of a transcription bubble on the promoter and the
loading of template DNA strand into the RNAP active site; these changes lead to the catalytically active
open complex (RPO) state. Recent cryo-electron mic...
