The kinetics of electron-transfer involved in reactions of reduction of 2,6-dichlorophenol indophenol and Fe(CN)3-(6) by L-ascorbic acid and reduction of ferric cytochrome c by both L-ascorbic acid and reduced hydroxylamine oxidoreductase were studied as a function of three parameters: ionic strength, pressure (1-2000 bar) and temperature (4-20 degrees C) using the high-pressure stopped-flow method. From measurements, the thermodynamic parameters of activation volume (delta V++), and, when possible, activation enthalpy and entropy (delta H++ and delta S++) have been calculated. We found, for these four systems, that the pressure has revealed solvation effects involved in electron-transfer. For the reduction of ferric cytochrome c by reduced hydroxylamine oxidoreductase (a cytochrome-to-cytochrome electron-transfer), we have not obtained evidence for a conformational change.
