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

/ure·ase/ (u´re-ās) an enzyme that catalyzes the hydrolysis of urea to ammonia and carbon dioxide; it is a nickel protein of microorganisms and plants that is used in clinical assays of plasma urea concentrations.

n.
An enzyme that catalyzes the hydrolysis of urea to form ammonium carbonate.

1 an enzyme used in the determination of urea in the blood or urine.
2 an enzyme that catalyzes the hydrolysis of urea to carbon dioxide and ammonia.
3 an antitumor enzyme.

urease

an enzyme that catalyses the hydrolysis of UREA into carbon dioxide and ammonia.

u·re·ase

(yūr'ē-ās)
An enzyme used as an antitumor agent; it is present in intestinal bacteria.

urease,

n an enzyme that divides urea into carbon dioxide and ammonia.

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.
