Direct electron transfer reactions of cytochrome c553 from Desulfovibrio vulgaris Hildenborough at indium oxide electrodes. 1987

K B Koller, and F M Hawkridge, and G Fauque, and J LeGall

The direct, heterogeneous, electron transfer reactions of cytochrome c553 from Desulfovibrio vulgaris Hildenborough have been studied at indium oxide optically transparent electrodes. These reactions have been studied using cyclic voltammetry and derivative cyclic voltabsorptometry and the kinetics of heterogeneous electron transfer is quasi-reversible. The thermodynamics and kinetics of electron transfer by this molecule can be studied at this electrode surface without the need for surface modification or the addition of surface promoters or mediators.
