Quantum-mechanical descriptions of proton transfer in biosystems containing hydrogen-bonded chains

Quantum-mechanical descriptions of proton transfer in biosystems containing hydrogen-bonded chains

Biochimica et Biophysica Acta 807(3): 272-277

A mechanism of proton transfer along the proton channel of (F0) ATP-synthetase of a membrane is suggested. In the small polaron model the charged fault (an excess of protons or a proton hole) transfer is considered in a longitudinal electric field along an assumed chain which is formed by hydroxyl groups connected by strong H-bonded chains. A number of kinetic parameters are estimated. The theoretical data are compared with the experimental results.
