Electron reactions with cytochrome c in ethylene glycol/water glass at-196 degrees C.
Low temperature gamma-irradiation and spectroscopy are used to study electron reactions with cytochrome c in aquo organic glass at-196 degrees C. Spectral data suggests that cytochrome c is reduced by electron at 196 degrees C. Raising the glass temperature reveals further changes in spectrum, suggesting that conformational changes may occur in cytochrome c molecule during stabilization of reductive process.
