RNA polymerase-binding protein RbpA (IPR025182)

Short name: RNApol-bd_RbpA

Overlapping homologous superfamilies

Family relationships



RbpA binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters [PMID: 23605043]. RbpA 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 inititation inhibitor rifampicin [PMID: 16629670].
