Function
function
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
Catalytic activity
- a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate + RNA(n+1)
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 Mg2+ ion per subunit.
Note: Binds 2 Zn2+ ions per subunit.

Interaction
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.
