Rapid and reversible binding of sulfide to [NiFe]-hydrogenases (particularly the enzyme from Desulfovibrio vulgaris) under weakly acidic conditions (pH 6) has been studied by protein film voltammetry, which tracks the formation of different species as a function of potential. Sulfide (most likely entering as H2S) rapidly attacks the active site during H2 oxidation. The inactive adduct is formed (and is stable) only at potentials substantially more positive than the comparable species formed w...Expand abstract
