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; CC -!- SUBUNIT: RNAP is composed of a core of 2 alpha, a beta and a beta' CC subunit. The core is associated with a delta subunit, and at least one CC of epsilon or omega. When a sigma factor is associated with the core CC the holoenzyme is formed, which can initiate transcription. CC -!- SIMILARITY: Belongs to the RNA polymerase subunit epsilon family.
