Activation of electron transfer reactions of the blue proteins. 1978

A S Brill

Thermal activation of electron transfer reactions of the blue proteins is considered in terms of vibronic coupling. Use of the electron paramagnetic resonance spectral distribution to obtain an estimate of the force constant for the relevant protein mode is proposed and demonstrated. This analysis leads to a model in which the configurations of the cupric and cuprous sites are displaced only a few degrees from each other, both being close to the configuration midway between planar and tetrahedral.

D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
