Function

function

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

Caution

Could be the product of a pseudogene. There are 3 rpoA-like genes in this organism (found in the inverted repeat). None of them are convincing as rpoA, and it may be that the functional gene is in the nucleus.

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 (By similarity).
