Genome Property Definition Page

NameRNA polymerase, bacterial
DescriptionThis property describes the bacterial multisubunit DNA-directed RNA polymerase (EC This property does not include sigma factors (at present), which are regulatory and varied, and so by definition describes the core enzyme rather than the holoenzyme. Subunit stochiometry is two alpha subunits to one each of beta and beta'. In Cyanobacteria and plastids, beta' is replaced by two proteins, one like the N-term of beta' (called gamma in Cyanobacteria and, confusingly, beta' in plastids) and one like the C-term of beta' (called beta' in Cyanobacteria and beta'' in plastids).
