Here we demonstrate that the isosteric hydroxylamine analogue of agmatine (AO-Agm) is a new and very potent (IC50 3•10−8 M) inhibitor of E. coli ADC hydroxylamine, assisted by intramolecular general base catalysis by the carboxylate group. Similar values have been consistently observed for reactions involving nucleophilic attack with proton transfer in the transition state (TS): e.g., for the reaction of hydroxylamine with 8- dimethylammonium. Hydroxylamine nitrate (HAN) is used to reduce Pu(IV) to Pu(III) in the separation of plutonium from uranium. HAN becomes unstable under certain conditions and has been known to explode, causing injury to humans including death. Hence, it is necessary to deactivate HAN once the reduction of plutonium is finished
