CC -!- FUNCTION: Promotes RNA polymerase assembly. Latches the N- and C-
CC terminal regions of the beta' subunit thereby facilitating its
CC interaction with the beta and alpha subunits. {ECO:0000256|HAMAP-
CC Rule:MF_00366}.
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|ARBA:ARBA00024550,
CC ECO:0000256|HAMAP-Rule:MF_00366};
CC -!- SUBUNIT: In cyanobacteria the RNAP catalytic core is composed of 2
CC alpha, 1 beta, 1 beta', 1 gamma and 1 omega subunit. When a sigma
CC factor is associated with the core the holoenzyme is formed, which can
CC initiate transcription. {ECO:0000256|HAMAP-Rule:MF_00366}.
CC -!- SIMILARITY: Belongs to the RNA polymerase subunit omega family.
CC {ECO:0000256|ARBA:ARBA00006711, ECO:0000256|HAMAP-Rule:MF_00366}.
