The extraordinary ability of Fe- and Ni-containing enzymes to catalyze rapid and efficient H(+)/H(2) interconversion--a property otherwise exclusive to platinum metals--has been investigated in a series of experiments combining variable-temperature protein film voltammetry with mathematical modeling. The results highlight important differences between the catalytic performance of [FeFe]-hydrogenases and [NiFe]-hydrogenases and justify a simple model for reversible catalytic electron flow in enzy ...[more]
