CC -!- FUNCTION: DNA-dependent RNA polymerase (RNAP) catalyzes the
CC transcription of DNA into RNA using the four ribonucleoside
CC triphosphates as substrates. Forms the clamp head domain.
CC {ECO:0000255|HAMAP-Rule:MF_00863}.
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_00863};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00863};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00863};
CC Note=Binds at least 2 Zn(2+) per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00863};
CC -!- SUBUNIT: Part of the RNA polymerase complex. {ECO:0000255|HAMAP-
CC Rule:MF_00863}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00863}.
CC -!- SIMILARITY: Belongs to the RNA polymerase beta' chain family.
CC {ECO:0000255|HAMAP-Rule:MF_00863}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAG20692.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
