    3.5.1.5 | hydroxyurea |
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 |

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 |

| 3.5.1.5 | more |
insecticidal activity of the jack bean ureases JBU and canatoxin. JBU is slightly less toxic than canatoxin. JBU isnot lethal to mice or rats when given intraperitoneally. JBU and canatoxin are able to induce activation of rabbit blood platelets |

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 |

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 |

platelet aggregation induced by Bacillus pasteurii urease is mediated by lipoxygenase-derived eicosanoids and secretion of ADP from the platelets through a calcium-dependent mechanism |
