glutaminase

 [gloo-tam´ĭ-nās]
an enzyme that catalyzes the splitting of glutamine into glutamic acid and ammonia.

glu·ta·min·ase

(glū-tam'in-ās),
An enzyme in kidney and other tissues that catalyzes the hydrolysis of l-glutamine to ammonia and l-glutamate; an important enzyme in urinary ammonia formation.

glutaminase

/glu·tam·i·nase/ (gloo-tam´ĭ-nās) an enzyme that catalyzes the deamination of glutamine to form glutamate and an ammonium ion; most of the latter are converted to urea via the urea cycle.

(glū-tam'in-ās)
An enzyme in kidney and other tissues that catalyzes the hydrolysis of l-glutamine to ammonia and l-glutamic acid; an important enzyme for urinary ammonia formation.
