== Function == | |||
[https://www.uniprot.org/uniprot/RBPA_MYCTU RBPA_MYCTU] Binds to RNA polymerase (RNAP), stimulating and stabilizing the formation of stable RNAP promoter complexes up to 2-fold from principal sigma factor SigA-dependent but not alternative sigma factor SigF-dependent promoters. Increases the affinity of core RNAP for SigA, increasing the transcriptional activity of RNAP. Unlike the case in M.smegmatis or S.coelicolor, has no effect on rifampicin inhibition of transcription. Has no effect on E.coli RNAP.<ref>PMID:22570422</ref> | |||
