title: [Proton transfer via the external proton channel of bacteriorhodopsin].
abstract: The process of proton transfer across the membrane via the external proton channel in bacteriorhodopsin is considered. A possible amino acid composition of the channel is suggested and the step-by-step mechanism of proton transfer is proposed which agrees with the experimental data. The rate of proton transfer between fixed centers at several chains of the channel was estimated for which the spectroscopic data are available.
