Interaction

Subunit

In plastids the minimal PEP RNA polymerase catalytic core is composed of four subunits: alpha, beta, beta', and beta''. When a (nuclear-encoded) sigma factor is associated with the core the holoenzyme is formed, which can initiate transcription.

Family & Domains

Features

Showing features for region, domain.

TypeIDPosition(s)Description
Region1-234Alpha N-terminal domain (alpha-NTD)
Domain29-232DNA-directed RNA polymerase RpoA/D/Rpb3-type
Region257-335Alpha 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.
