3.A.1.131.1
The 2 or 3 component bacitracin-resistance efflex pump, BcrAB or BcrABC (Podlesek et al., 1995; Bernard et al., 2003) (BcrA is most similar to SpaF (3.A.1.124.2), but BcrB (5-6 TMSs) is only distantly related to other ABC2-type membrane proteins (Wang et al., 2009). BcrC is not sufficiently similar to detect similarity in BLAST searches. BcrC (5TMSs) belongs to the PAP2 phosphatase superfamily and may not be a contituent of the BcrAB transporter. Transcription is regulated by BcrR, a one-component transmembrane signal transduction system (Darnell et al. 2019).
