[Reaction kinetics of electron phototransfer in an eosin-casein complex]

The role of protein matrix in the process of charge photorespiration on the model of eosin-casein complex was studied. We have also studied the kinetics of the electron transfer reactions being photosensitized by free eosin and eosin sorbed on casein in the donor (cystein) - acceptor (methylviologen) system. When eosin is sorbed on protein a 10-fold increase of the probability relation of non-retrospective direct electron transfer to the restrospective one was observed.
