Function |
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. |
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:Cyanobacteria>
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:Cyanobacteria>
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. |
else case <OG:Chloroplast>
Subunit |
In plastids the minimal PEP RNA polymerase catalytic core is composed of four subunits: alpha, beta, beta', and beta''. When a (nuclear-encoded) sigma factor is associated with the core the holoenzyme is formed, which can initiate transcription. |
Subcellular location |
Plastid, chloroplast. |
end case
Similarity |
Belongs to the RNA polymerase beta chain family. |

Comments |
Fused with rpoC in Helicobacter species and at least some Wolbachia, but not in other epsilon proteobateria. CHLVU, ODOSI and PSEAK have large inserts, HETCA has a deletion, CHLRE is split. None are used in the alignment. |
