The high efficiency of photostimulated electron-transfer (ET) reactions in biological systems, including within the structure of reaction centres, attracts attention of many researchers. Analysis of the main factors determining the rate of such reactions is important in a fundamental aspect and in terms of creating artificial systems for storage and conversion of energy. As revealed, the ET in biological systems occurs as consecutive ET in the structure of proteins between the metal-bearing centres or the organic donor–acceptor groups at a distance of 5–25 A. In this regard, series of experiments related to ET in the structure of proteins are carried out. The kinetics of ET in bacterial reaction centres (RC) is investigated. The processes of relaxation and photoinduced structural changes in molecular complexes of the Rhodobacter spharoides RC in the process of the intramolecular ET. Results of both experimental study of the dependence of microvelocities of transition between donor and acceptor on the intensity and time illumination of RC and theoretical analysis of relaxation curves using wavelet transforms are presented.
