X-ray-induced catalytic active-site reduction of a multicopper oxidase: structural insights into the proton-relay mechanism and O(2)-reduction states

During X-ray data collection from a multicopper oxidase (MCO) crystal, electrons and protons are mainly released into the system by the radiolysis of water molecules, leading to the X-ray-induced reduction of O(2) to 2H(2)O at the trinuclear copper cluster (TNC) of the enzyme. In this work, 12 cryst...
