Novel Phosphotransferase Systems Revealed by Bacterial Genome Analysis: The Complete Repertoire of PTS Genes in Pseudomonas Aeruginosa

J Mol Microbiol Biotechnol. 1999 Nov;1(2):289-93.


We herein describe all genes encoding constituents of the phosphoenolpyruvate:sugar phosphotransferase system (PTS) in the 6Mbp genome of the opportunistic human pathogen, Pseudomonas aeruginosa. Only four gene clusters were found to encode identifiable PTS homologues. These genes clusters encode novel multidomain proteins, two complete sugar-specific PTS phosphoryl transfer chains for the metabolism of fructose and N-acetylglucosamine, and a complex regulatory system that may function to coordinate carbon and nitrogen metabolism. No previously characterized organism has been shown to exhibit such a novel and restricted complement of PTS proteins.
