Four-electron Reduction of Dioxygen by a Multicopper Oxidase, CueO, and Roles of Asp(112) and Glu(506) Located Adjacent to the Trinuclear Copper Center

The mechanism of the four-electron reduction of dioxygen by a multicopper oxidase, CueO, was studied based on reactions of single and double mutants with Cys(500), a type I copper ligand, and the noncoordinating Asp(112) and Glu(506), which form hydrogen bonds with the trinuclear copper center direc...
