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.

Type
IDPosition(s)Description
Region1-228Alpha N-terminal domain (alpha-NTD)
Domain18-225DNA-directed RNA polymerase RpoA/D/Rpb3-type
Region241-347Alpha 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.
