CC -!- FUNCTION: DNA-dependent RNA polymerase (RNAP) catalyzes the
CC transcription of DNA into RNA using the four ribonucleoside
CC triphosphates as substrates. {ECO:0000256|HAMAP-Rule:MF_00320}.
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:0000256|HAMAP-Rule:MF_00320};
CC -!- SUBUNIT: Part of the RNA polymerase complex. {ECO:0000256|HAMAP-
CC Rule:MF_00320}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00320}.
CC -!- SIMILARITY: Belongs to the archaeal Rpo3/eukaryotic RPB3 RNA polymerase
CC subunit family. {ECO:0000256|ARBA:ARBA00025804, ECO:0000256|HAMAP-
CC Rule:MF_00320}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00320}.
