Function
function
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
Miscellaneous
In L.terrestris the gene for this protein is split in two.
Catalytic activity
- RNA(n) + a ribonucleoside 5'-triphosphate = RNA(n+1) + diphosphate

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 (By similarity).
