Proline is an efficient source of both carbon and nitrogen for many bacterial species. In Bacillus subtilis, the proline utilization pathway, encoded by the putBCP operon, is inducible by proline. Here, we show that this induction is mediated by PutR, a proline-responsive transcriptional activator of the PucR family. When other amino acids are present in the medium, proline utilization is prioritized through transient repression by CodY, a global transcriptional regulator in Gram-positive bacter ...[more]
