Most strains produce a powerful urease enzyme, which rapidly hydrolyzes urea to ammonia and carbon monoxide; exceptions are some Providencia strains.
22.
Other graphics programs such as DeepView ( example : urease ) and MolMol ( example : SH2 domain ) also produce ribbon images.
23.
Nitrifying organisms are biomass via the Calvin Cycle, and harvest energy by oxidizing ammonia ( the other product of urease ) to nitrite.
24.
It is positive for urease production, is oxidase negative, and can use glucose, sucrose, and lactose to form acid products.
25.
The notable distinction between " Wautersiella falsenii " and " Empedobacter brevis " is that the latter is urease negative.
26.
The test detects the characteristic enzyme urease, produced by " H . pylori ", by a reaction that produces ammonia from urea.
27.
In 1926, James B . Sumner, an assistant professor at Cornell University, showed that urease is a protein by examining its crystallized form.
28.
All bacterial ureases are solely cytoplasmic, except for Helicobacter pylori urease, which along with its cytoplasmic activity, has external activity with host cells.
29.
On leaving school he became a junior laboratory technician for PhD degree in 1953 for a thesis entitled " Studies on gastric urease ".
30.
Ebrotidine has anti-" Helicobacter pylori " activity via inhibition of the urease enzyme and the proteolytic and mucolytic activities of the bacterium.
