Function and interactions

EC number 2.7.7.6
Catalytic activity CATALYTIC ACTIVITY: Reaction=RNA(n) + a ribonucleoside 5'-triphosphate = RNA(n+1) + diphosphate; Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395; EC=2.7.7.6; Evidence={ECO:0000255|HAMAP-Rule:MF_01321};
Subunit structure SUBUNIT: The RNAP catalytic core consists of 2 alpha, 1 beta, 1 beta' and 1 omega subunit. When a sigma factor is associated with the core the holoenzyme is formed, which can initiate transcription. {ECO:0000255|HAMAP-Rule:MF_01321}.
