- n. an enzyme that catalyzes the hydrolysis of urea into carbon dioxide and ammonia; is present in intestinal bacteria
Tests showed that urease is also a protein, making this the first ever protein to be crystallized.
H. pylori uses an enzyme called urease to attach to and infect the inside of the stomach.
An enzyme called urease is produced by certain bacteria in the urinary tract.
H. pylori depends on a protein called urease to bind to and infect the stomach lining, and so the scientists created a urease antibody called IgY-urease they then fortified the yoghurt with.
In 1926, however, in connection with his studies of a special enzyme "urease", James B. Sumner of Cornell University,
Sumner had in 1926 crystalized an enzyme, urease, from jack beans and suggested that the crystals were the pure protein.
I did my famous self experimentation and the early urease tests were developed.
Sumner, USA (Nobel Prize 1946) crystallizes the enzyme urease and demonstrates that it is a protein.
His isolation and crystallization of urease met with mixed response; it was ignored or disbelieved by most biochemists, but it brought him a full professorship in 1929.
The plan fell through, however, because Effront thought Sumner's idea of isolating urease was ridiculous.
