Divergent structure and regulatory mechanism of proline catabolic systems: characterization of the putAP proline catabolic operon of Pseudomonas aeruginosa PAO1 and its regulation by PruR, an AraC/XylS family protein

Research reveals structural, organizational, and regulatory diversity in the proline catabolic genes between Pseudomonas aeruginosa and P. putida and the genetic processes involved influence the development of proline catabolism in these bacteria. Data show that the proline utilization system from P. aeruginosa differs from that of P. putida in terms of putA gene.
