Function

RBPA_STRCO Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters. Stimulates transcription from several principal sigma factor HrdB (SigA)-dependent promoters but not from a SigR-dependent promoter. Stimulation occurs in the presence of the transcription initiation inhibitor rifampicin (Rif).[HAMAP-Rule:MF_01483]^{[1] [2]}
