Pressure Tuning Voltammetry. Reaction Volumes for Electron Transfer in Cytochrome c and Ruthenium-Modified Cytochromes c

This paper presents a detailed study of the effect of pressure (up to 200 MPa) on the redox potential of cytochrome c and ruthenated cytochrome c using differential pulse voltammetry (DPV) as well as CV. The results of this study clearly demonstrate that horse heart cytochrome c exhibits no major ch...

Summary:This paper presents a detailed study of the effect of pressure (up to 200 MPa) on the redox potential of cytochrome c and ruthenated cytochrome c using differential pulse voltammetry (DPV) as well as CV. The results of this study clearly demonstrate that horse heart cytochrome c exhibits no major change in volume during electron transfer and that the observed volume changes can largely be accounted for in terms of processes that occur on the redox partner, i.e. the reference electrode and/or the ruthenium ammine complexes. 39 refs., 6 figs., 1 tab.
