Protein namei

  • Recommended name:
    DNA-directed RNA polymerase subunit beta (EC:2.7.7.6)

Subunit structurei

  • 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.
  • 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.

Sequence similaritiesi

Functioni

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

Catalytic activityi

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