Abstract

The reaction center of Chloroflexus aurantiacus and Rhodobacter sphaeroides mutation of RC`s was investigated. To describe the kinetic of the Chloroflexus aurantiacus RC's we use incoherent model of electron transfer. It was shown that the asymmetry in electronic coupling must be included to explain the experiments. For the description of Rhodobacter sphaeroides H(M182)L mutation we used partially coherent as incoherent models of electron transfer. These two models are discussed with regard to the observed electron transfer kinetics. It can be concluded that partially coherent model is more adequate. We predict some new electron pathways for describing the kinetic of RC's and some mutation.
