Electric-field effects on the [FeFe]-hydrogenase active site
Electric field effects from the protein environment and an electrode are unravelled at the active site of [FeFe] hydrogenases by quantum calculations.
Production of H2 at fast rates using a nickel electrocatalyst in water –acetonitrile solutions
The [Ni(PPh2NC6H4OH2)2]+2 electrocatalyst produces H2 solely from H3O+ in a mostly H2O environment at a rate of 170 000 s−1 and an overpotential of 470 mV.
Structural foundations for the O2 resistance of Desulfomicrobium baculatum [NiFeSe]-hydrogenase
Crystallographic analyses of an O2-resistant [NiFeSe]-hydrogenase show how O2 reacts with a selenocysteine and partially characterizes an enzyme activation pathway.
The mechanism of inhibition by H2 of H2-evolution by hydrogenases
We demonstrate that whether or not hydrogen evolution by FeFe or NiFe hydrogenase is significantly inhibited by H2 is not a consequence of active site chemistry, but rather relates to H2 transport within the enzyme.
Catalytic hydrogen production by a Ni–Ru mimic of NiFe hydrogenases involves a proton-coupled electron transfer step
Hydrogen evolution from weak acids catalyzed by a structural mimic of the active site of NiFe hydrogenases [Ni(xbsms)Ru(C6Me6)Cl]+ proceeds through proton-coupled electron transfer steps.
