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   -!- 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}.
