The proposed reaction mechanism of CO dehydrogenase with H2. Catalysis proceeds by displacement of H2O from the copper of the binuclear center by H2, followed by successive deprotonations as shown to introduce a pair of reducing equivalents into the highly delocalized redox-active orbital of the binuclear center.
