Electrochemical study of the electron exchange between cytochrome c3 and hydrogenase from Desulfovibrio desulfuricans Norway.
The kinetics of the reduction of the Desulfovibrio desulfuricans Norway cytochrome c3 by its physiological partner hydrogenase, in the presence of hydrogen, was investigated by an electrochemical method; from cyclic voltammetry experiments a value of 3 X 10(7) M-1 s-1 was obtained for the second-order rate constant. Results are discussed in terms of specific interactions between physiological partner proteins.
