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:0000255|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:0000255|HAMAP-Rule:MF_00366};
CC   -!- SUBUNIT: The RNAP catalytic core consists of 2 alpha, 1 beta, 1 beta'
CC       and 1 omega subunit. When a sigma factor is associated with the core
CC       the holoenzyme is formed, which can initiate transcription.
CC       {ECO:0000255|HAMAP-Rule:MF_00366}.
CC   -!- SIMILARITY: Belongs to the RNA polymerase subunit omega family.
CC       {ECO:0000255|HAMAP-Rule:MF_00366}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAW74402.1; Type=Erroneous initiation; Evidence={ECO:0000305};
