Protein

DNA-directed RNA polymerase subunit omega

Gene

rpoZ

Organism
Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)

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.UniRule annotation
