CC -!- FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription of
CC DNA into RNA using the four ribonucleoside triphosphates as substrates.
CC {ECO:0000255|HAMAP-Rule:MF_01321, ECO:0000255|HAMAP-Rule:MF_01322}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC EC=2.7.7.6; Evidence={ECO:0000255|HAMAP-Rule:MF_01321,
CC ECO:0000255|HAMAP-Rule:MF_01322};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01322};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01322};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01322};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01322};
CC -!- SUBUNIT: The RNAP catalytic core consists of 2 alpha, 1 beta/beta' and
CC 1 omega subunit. When a sigma factor is associated with the core the
CC holoenzyme is formed, which can initiate transcription.
CC {ECO:0000255|HAMAP-Rule:MF_01321, ECO:0000255|HAMAP-Rule:MF_01322}.
CC -!- MISCELLANEOUS: Fusion of rpoB and rpoC occurs naturally in Helicobacter
CC species and at least some Wolbachia; the protein has been artificially
CC split in two in H.pylori. The split protein seems to function normally.
CC {ECO:0000250|UniProtKB:O25806}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the RNA polymerase
CC beta chain family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the RNA polymerase
CC beta' chain family. {ECO:0000305}.
