| Type: | Family | Name: | DNA-directed RNA polymerase subunit D (Rpo3) |
| 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 D subunit (RpoD) of the archaeal DNA-directed RNA polymerase. It has also being named Rpo3 following the eukaryotic nomenclature []. | Short Name: | RNAP_D |
