ABSTRACT
The coupling of electron and proton transport in the vicinity of the secondary quinone QB in the reaction center of bacteria and photosystem II of higher plants was investigated. The energy levels and wave functions of the proton in the system QB--histidine L 190 were calculated. It was shown that the proton of histidine forms a hydrogen bond with the doubly reduced quinone QB2-. A new scheme of proton transport through histidine L 190 and its coupling with electron transport was proposed.
