This bacterium produces urease, alkaline phosphatase, pyrrolidonyl arylamidase, beta-galactosidase, and beta-glucuronidase, and hydrolyses aesculin and Tween 80.

Struvite stones are generated by infections of urease-containing microorganisms that are capable of hydrolyzing the urea in the urine to carbon dioxide and ammonia.
33.
It is part of the gastric mucosa of cats, and is Gram-negative, microaerophilic, urease-positive, and spiral-shaped.
34.
As of now, the only known factor that distinguishes these two species is that " L . fusiformis " is positive for urease.
35.
It is important to note that the coordination of urea to the active site of urease has never been observed in a resting state of the enzyme.
36.
For the second mechanism, scientists suggest that probiotics prevent the growth of urease-producing bacteria, which typically occurs in the second stage of rotavirus diarrhea.
37.
H . pyloris produces an enzyme, urease, which converts urea to ammonia and bicarbonate that neutralize the stomach acid and allow the organism to gain a foothold.
38.
In 1926, James B . Sumner showed that the enzyme urease was a pure protein and crystallized it; he did likewise for the enzyme catalase in 1937.
39.
Urea is an important by-product of this reaction sequence because it makes ammonicial ammonia ( urease-mediated ) that is available to support intermediary nitrogen metabolism.
40.
Unlike other bacterial versions of urease, the type produced by H . pylori is unique in that it has a spherical shape, with a cavity in the middle.
