additional information
-
ureases of Canavalia ensiformis are entomotoxic upon the release of internal peptides by insects digestive enzymes
-
nitrogen metabolism, could be crucial for the pathogen's survival in nutrient-limited microenvironments where urea is the sole nitrogen source
metabolism
the enzyme catalyses the rapid hydrolysis of urea during the last step of the organic nitrogen mineralization

-
effects of urease added to rabbit platelets are assessed turbidimetrically. Fluorescein-labelled HPU bound to platelets but not to erythrocytes. HPU induces aggregation of rabbit platelets accompanied by ATP secretion. No correlation is found between platelet activation and ureolytic activity of HPU
physiological function
-
growth studies demonstrate that Edwardsiella ictaluri is unable to grow at pH 5 in the absence of urea but is able to elevate the environmental pH from pH 5 to pH 7 and grow when exogenous urea is available
physiological function
-
the bacterium typically colonizes the mucosal lining of the stomach, where the increase in pH of the strongly acidic environment allows the bacterium that requires pH 6-8 to grow, to persist in the hostile conditions. Concomitantly it incurs damage to the host tissue, thereby giving rise to gastritis and gastroduodenal ulcers. The damaging factors are ammonia and monochloramine
physiological function
-
the biosynthesis of the active metal-bound form of the nickel-dependent enzyme urease involves the formation of a lysine-carbamate functional group concomitantly with the delivery of two Ni2+- ions into the precast active site of the apoenzyme and with GTP hydrolysis. In the urease system, this role is performed by UreG, an accessory protein belonging to the group of homologous P-loop GTPases
physiological function
-
urease is required for proliferation and virulence and for intracellular replication. Intracellular replication of wild-type Edwardsiella ictaluri is significantly enhanced when urea is present, indicating that urease plays an important role in intracellular survival and replication, possibly through neutralization of the acidic environment of the phagosome

physiological function
-
neutralization of acid by ammonia is essential for gastric Helicobacter pylori colonization
physiological function
-
the enzyme is a virulence factor for ureolytic bacterial human pathogens, but it is also necessary to convert urea, the most worldwide used fertilizer, into forms of nitrogen that can be taken up by crop plants
physiological function
the enzyme that catalyses the hydrolysis of urea, is a virulence factor for a large number of ureolytic bacterial human pathogens
physiological function
Cryptococcus gattii urease plays an important role in virulence, in part possibly through enzyme activity-independent mechanism(s)
physiological function
urease is a virulence factor in several human pathogens, while causing severe environmental and agronomic problems
