Sigma factor can direct the tight binding of RNA polymerase to promoters and place the enzyme in a position to initiate transcription so that it can stimulate initiation of transcription. Because initiation is a rate-limiting step in transcription, the σ factor can also stimulate elongation because...

BACTERIAL RNA polymerase consists of a core (α2ββ′) and a sigma (σ) factor which form the active holoenzyme (α2ββ′σ) (ref. 1). Significant differences in size of the β and β′ subunits occur in the enzymes from various bacterial species2. The
