Molybdenum | the enzyme accelerates reaction rate via base-catalyzed chemistry in which a Mo-OH group undertakes nucleophilic attack on the carbon center to be hydroxylated, with concomitant hydride transfer to a catalytically essential Mo=S group in the molybdenum coordination sphere. This chemistry appears to proceed via obligate two-electron chemistry rather than in individual steps to yield a reduced enzyme product complex with product coordinmated to the active site molybdenum by means of the newly introduced hydroxyl group in a sinple end-on fashion | Bos taurus |

xanthine + H2O + O2 | the enzyme accelerates reaction rate via base-catalyzed chemistry in which a Mo-OH group undertakes nucleophilic attack on the carbon center to be hydroxylated, with concomitant hydride transfer to a catalytically essential Mo=S group in the molybdenum coordination sphere. This chemistry appears to proceed via obligate two-electron chemistry rather than in individual steps to yield a reduced enzyme product complex with product coordinmated to the active site molybdenum by means of the newly introduced hydroxyl group in a sinple end-on fashion. Product displacement by hydroxide and electron transfer to other redox-active centers in the enzyme complete the catalytic sequence | Bos taurus | uric acid + H2O2 | - |
