摘要：

Copper amine oxidases have a complex reaction cycle that converts a primary amine and molecular oxygen into the aldehyde, ammonia and hydrogen peroxide. Coupling structural studies of freeze-trapped reaction intermediates in crystals with kinetic and spectroscopic experiments in solution has generated a detailed molecular picture of catalysis. Although dioxygen has been directly observed bound to the copper at a late stage in the reaction cycle, whether copper is the initial binding site remains controversial.
