Abstract

An artificial metalloenzyme acting as a functional biomimic of hydrogenase enzymes was activated by assembly via covalent attachment of the molecular complex, [Ni(PN^glycineP)₂]^2-, within a structured protein scaffold. Electrocatalytic H₂ production was observed from pH 3.0 to 10.0 for the artificial enzyme, while no electrocatalytic activity was observed for similar [Ni(PNP)₂]²⁺ systems.
