title: Electrochemical study of the electron exchange between cytochrome c3 and hydrogenase from Desulfovibrio desulfuricans Norway.
abstract: 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.
