Protein existenceInferred 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_00411

Catalytic activity

Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). HAMAP MF_00411

Post-translational modification

This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation Potential. HAMAP MF_00411

Sequence similarities

Belongs to the RNA polymerase beta' chain family.

Contains 1 DOD-type homing endonuclease domain.
