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 RHEA:21248: a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate + RNA(n+1)
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.
