FUNCTION | DNA-dependent RNA polymerase (RNAP) catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Forms the clamp head domain. |
CATALYTIC ACTIVITY | Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate + RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA- COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395; EC=2.7.7.6; |
case <FTGroup:3> | |
COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
end case | |
case <FTGroup:1> and <FTGroup:2> | |
COFACTOR | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Note=Binds at least 2 Zn(2+) per subunit. |
end case | |
SUBUNIT | Part of the RNA polymerase complex. |
SUBCELLULAR LOCATION | Cytoplasm. |
SIMILARITY | Belongs to the RNA polymerase beta' chain family. |

Comments | Intein deleted in METJA. In some archaea (including Thaumarchaeota and Korarchaeum cryptofilum) Rpo1N and Rpo1C are fused. A third Zn(2+) is present in S.acidocaldarius; the residues which bind this Zn are conserved in other known Sulfolobales and a few other archaea. |
