title: Induction of histidine-degrading enzymes in Pseudomonas aeruginosa.
abstract: Urocanate but not histidine was able to induce formation of histidine-degrading enzymes in a histidine ammonia-lyase-deficient mutant of Pseudomonas aeruginosa. The results, in conjunction with others reported previously, indicate that urocanate, the first intermediate, is the physiological inducer of the pathway.
