Comments
[?]
| case not <OG:Chloroplast> | |
| FUNCTION | Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits. |
| else case <OG:Chloroplast> | |
| FUNCTION | May be involved in RNA polymerase activity. |
| SUBCELLULAR LOCATION | Plastid, chloroplast. |
| end case | |
| CATALYTIC ACTIVITY | Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate + RNA(n+1); 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; |
| case not <OG:Chloroplast> and not <OC:Cyanobacteriota> | |
| 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. |
| else case <OC:Cyanobacteriota> | |
| SUBUNIT | In cyanobacteria the RNAP catalytic core is composed of 2 alpha, 1 beta, 1 beta', 1 gamma and 1 omega subunit. When a sigma factor is associated with the core the holoenzyme is formed, which can initiate transcription. |
| end case | |
| SIMILARITY | Belongs to the RNA polymerase subunit omega family. |
