Induction of histidine-degrading enzymes in Pseudomonas aeruginosa. 1970

C P Newell, and T G Lessie

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.

UI	MeSH Term	Description	Entries
D007093	Imidazoles	Compounds containing 1,3-diazole, a five membered aromatic ring containing two nitrogen atoms separated by one of the carbons. Chemically reduced ones include IMIDAZOLINES and IMIDAZOLIDINES. Distinguish from 1,2-diazole (PYRAZOLES).
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D011550	Pseudomonas aeruginosa	A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.
