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_01323}.
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_01323};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01323};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01323};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01323};
CC Note=Binds 1 Zn(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01323};
CC -!- SUBUNIT: In cyanobacteria the RNAP catalytic core is composed of 2
CC alpha, 1 beta, 1 beta', 1 gamma and 1 omega subunit. When a sigma
CC factor is associated with the core the holoenzyme is formed, which can
CC initiate transcription. {ECO:0000255|HAMAP-Rule:MF_01323}.
CC -!- SIMILARITY: Belongs to the RNA polymerase beta' chain family. RpoC1
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01323}.
