| Аннотация | A model of influence of non-heme Fe2+ ion on kinetics of electron transfer between quinone anion-radicals QA- and QB- in bacterial reaction centres is proposed and investigated. Physical mechanism of the influence is associated with singlet-triplet transitions in QA-QB- pair caused by interactions with paramagnetic Fe2+. The model incorporates exchange couplings between the particles and zero-field splittings in high-spin Fe2+. These interactions are shown to catalyze electron transfer in triplet pairs and alter the reaction yield significantly. |
