ChainPRO_00003534821-717DNA-directed RNA polymerase subunit beta'

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.
