Function
Functions as both a membrane-bound sensor and transducer of bacitracin availability to activates transcription of the bcrABD operon in the presence of bacitracin (PubMed:15388429, PubMed:18227063, PubMed:30777814). Binds specifically to two inverted repeat sequences on the bcrABD promoter, irrespective of bacitracin concentration (PubMed:18227063).
