urease

 [u´re-ās]
an enzyme that catalyzes the decomposition of urea to ammonia and carbon dioxide.

u·re·ase

(yūr'ē-ās),
An enzyme that catalyzes the hydrolysis of urea to carbon dioxide and ammonia; used as an antitumor enzyme; it is present in intestinal bacteria and accounts for most of the ammonia generated from urea in mammals.

urease

an enzyme that catalyzes the decomposition of urea to ammonia and carbon dioxide, present in high activity in ruminal microflora.

urease inhibitors
compounds that inhibit or block the activity of urease, most commonly used in the management of struvite urolithiasis. See also acetohydroxamic acid.
urease tests
a biochemical test used in the identification of some bacteria such as Proteus spp. Using urea agar or broth, bacteria producing urease will cause the formation of ammonia, which is detected by phenol red in the medium.
