Regulation of proline utilization in enteric bacteria: cloning and characterization of the Klebsiella put control region.

Abstract excerpt

Enteric bacteria can grow on proline as the sole nitrogen and carbon source. Expression of the proline utilization (put) operon in Klebsiella strains and Escherichia coli is responsive to nitrogen regulation. In contrast, Salmonella typhimurium cannot activate put operon expression when growing in medium with glucose as a carbon source and proline as the sole nitrogen source. To compare nitrogen regulatory sites...
