REACTION DIAGRAM
hydroxyurea
HCO3- + NH4+ + NH2OH
-
using kinetic isotope effects it is shown that hydroxyurea exhibits biphasic kinetics with a rapid burst phase, followed by a very slow plateau phase. The plateau phase is attributed to irreversible substrate inhibition. The product, hydroxylamine, is shown to be a weak but reversible inhibitor of urease, it is not the cause of the plateau phase

urea can be utilized as a nitrogen source via a urease-dependent pathway, the ureolysis can protect the organism against environmental acidification at physiologically relevant pH values. Therefor, urease can confer to Actinomyces naeslundii critical selective advantages over nonureolytic organisms in dental plaque

urease protects Helicobacter pylori against the acidic environment of the stomach, the enzyme acts as cytotoxin, with human gastric cells especially susceptible to its activity and disrups cell tight junctions in such a manner that the cells remain viable but an ionic flow between the cells occurs

the urease impairs growth of selected phytopathogenic fungi at sub-micromolar concentrations. This antifungal property of ureases is not affected by treatment of the proteins with an irreversible inhibitor of the ureolytic activity. Ureases probably contribute to the plant arsenal of defense compounds against predators and phytopathogens

Cotton seed urease displays low ureolytic activity but exhibits potent antifungal properties at sub-micromolar concentrations against different phytopathogenic fungi. The antifungal effect of cotton urease persists after treatment with an irreversible inhibitor of its enzyme activity. The data suggest an important role of the protein in plant defense
