Protein Domain : IPR019969

Type:  Family Name:  DNA-directed RNA polymerase subunit B (Rpo2)
Description:  DNA-directed RNA polymerases,also known as DNA-dependent RNA polymerases, are responsible for the polymerisation of ribonucleotides into a sequence complementary to the template DNA. Eukaryotes have three different DNA-directed RNA polymerases (RNAPs), Pol I, II, and III, whereas Archaea and Bacteria have single enzymes.RNAPs are multisubunit enzymes. Archaeal RNAP is closely related to eukaryotic RNAP II [], which consists of 12 subunits. Archaeal RNAP has an additional subunit, Rpo13, with no orthologue in the eukaryotic enzyme []. This entry represents the archaeal DNA-directed RNA polymerase subunit B (RpoB). The name Rpo2 has been proposed for this subunit based on eukaryotic terminology [], as it is the homologue of eukaryotic Rpb2. Short Name:  RNAP_B
