ChainPRO_00003004431-1247DNA-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 (By similarity).
