Protein

DNA-directed RNA polymerase subunit omega

Gene

rpoZ

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Promotes RNA polymerase assembly. Latches the N- and C-terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.

Catalytic activityi

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

Interactioni

Subunit structurei

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.1 Publication
