Sigma factor: Art & Products

A sigma factor (σ factor or specificity factor) is a protein needed for initiation of transcription in bacteria. It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase (RNAP) to gene promoters. They are also found in plant chloroplasts as a part of the bacteria-like plastid-encoded polymerase (PEP). It is…
