Function
function
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
Catalytic activity
- RNA(n) + a ribonucleoside 5'-triphosphate = RNA(n+1) + diphosphate
Cofactor
Note: Binds 1 Zn2+ ion per subunit.

Subcellular Location
Interaction
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.
