R.R. Burgess, in Encyclopedia of Genetics, 2001 History Sigma factors are subunits of all bacterial RNA polymerases. They are responsible for determining the specificity of promoter DNA binding and control how efficiently RNA synthesis (transcription) is initiated. The first sigma factor discovered wa...
In 1968 it was discovered that in addition to the core RNA polymerase another subunit, the sigma factor, was needed. The sigma factor binds to core RNA polymerase to form a holoenzyme and directs selective binding to the bacterial promoter at the beginning of a gene and efficient initiation ...
