Protein attributes

Sequence length	1407 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. HAMAP MF_01322
Catalytic activity	Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). HAMAP MF_01322
Subunit structure	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 By similarity.
Sequence similarities	Belongs to the RNA polymerase beta' chain family.
