Mechanism and properties of electron transfer in protein molecules

Abstract

Excitation of extra-electron is caused by the energy released in ATP hydrolysis in protein molecules. The excitation can self-trap as a soliton through interaction with deformation of amino acids. When donors and acceptors are distributed along the protein molecular chains close enough, the electrons in the donors can be transferred by the soliton due to the interaction between them. Authors calculate the speed and kinetic coefficient of the electron transfer from the donors and acceptors in the molecular chains with cubic anharmonicity by non-equilibrium statistical theory. Some interesting results are obtained.
