Abstract
In bacteria, σ subunits direct the catalytically competent RNA polymerase core enzyme to promoters. Recent advances in our understanding of bacterial RNA polymerase reveal that σ subunits are intimately involved in all aspects of transcription initiation including promoter location, promoter melting, initiation of RNA synthesis, abortive initiation and promoter escape.
