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_00059}.
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_00059};
CC -!- SUBUNIT: Homodimer. The RNAP catalytic core consists of 2 alpha, 1
CC beta, 1 beta' and 1 omega subunit. When a sigma factor is associated
CC with the core the holoenzyme is formed, which can initiate
CC transcription. {ECO:0000255|HAMAP-Rule:MF_00059}.
CC -!- DOMAIN: The N-terminal domain is essential for RNAP assembly and basal
CC transcription, whereas the C-terminal domain is involved in interaction
CC with transcriptional regulators and with upstream promoter elements.
CC {ECO:0000255|HAMAP-Rule:MF_00059}.
CC -!- SIMILARITY: Belongs to the RNA polymerase alpha chain family.
CC {ECO:0000255|HAMAP-Rule:MF_00059}.
