Function

function

DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Interaction

Subunit

Homodimer. 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.

Features

Showing features for region.

TypeIDPosition(s)Description
Region1-235Alpha N-terminal domain (alpha-NTD)
Region249-329Alpha C-terminal domain (alpha-CTD)

Domain

The N-terminal domain is essential for RNAP assembly and basal transcription, whereas the C-terminal domain is involved in interaction with transcriptional regulators and with upstream promoter elements.

Sequence similarities

Belongs to the RNA polymerase alpha chain family.
