The −11A of promoter DNA and two conserved amino acids in the melting region of σ(70) both directly affect the rate limiting step in formation of the stable RNA polymerase-promoter complex, but they do not necessarily interact
Formation of the stable, strand separated, ‘open’ complex between RNA polymerase and a promoter involves DNA melting of approximately 14 base pairs. The likely nucleation site is the highly conserved −11A base in the non-template strand of the −10 promoter region. Amino acid residues Y430 and W433 o...
