Adv. , 6, eaaz8181, 2020.06, The study of hydrogenase enzymes (H2ases) is necessary because of their importance to a future hydrogen energy
economy. These enzymes come in three distinct classes: [NiFe] H2ases, which have a propensity toward H2 oxidation;
[FeFe] H2ases, which have a propensity toward H2 evolution; and [Fe] H2ases, which catalyze H− transfer. Modeling
these enzymes has so far treated them as different species, which is understandable given the different cores and
ligand sets of the natural molecules. Here, we demonstrate, using x-ray analysis and nuclear magnetic resonance,
infrared, Mössbauer spectroscopies, and electrochemical measurement, that the catalytic properties of all three
enzymes can be mimicked with only three isomers of the same NiFe complex..
