CC -!- FUNCTION: DNA-dependent RNA polymerase (RNAP) catalyzes the
CC transcription of DNA into RNA using the four ribonucleoside
CC triphosphates as substrates. The Rpo2 subunit (Rpo2N and Rpo2C in this
CC organism) is implicated in DNA promoter recognition and in nucleotide
CC binding. {ECO:0000250|UniProtKB:B8YB55}.
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:0000250|UniProtKB:P11513};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:B8YB55};
CC Note=Binds 1 Zn(2+) per subunit. {ECO:0000250|UniProtKB:B8YB55};
CC -!- SUBUNIT: Part of the RNA polymerase complex.
CC {ECO:0000250|UniProtKB:B8YB55}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:B8YB55}.
CC -!- SIMILARITY: Belongs to the RNA polymerase beta chain family.
CC {ECO:0000305}.
