Protein attributes

Sequence length	1342 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. HAMAP MF_01321
Catalytic activity	Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). HAMAP MF_01321
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.
Sequence caution	The sequence ABJ03449.1 differs from that shown. Reason: Erroneous initiation.
