The processes of electron transfer in cyanobacterial photosystem I (PS I) and photoelectric methods of the studies were reviewed. Particular emphasis was placed on structural and kinetic characteristics of the electron transport chain. The electrogenicity in PS I complex and its interaction with natural donors (plastocyanin, cytochrome c6), natural acceptors (ferredoxin, flavodoxin), and artificial acceptors and donors (methyl viologen and other redox dyes) were studied. On the basis of… Expand

Correlation of electron transfer rate in photosynthetic reaction centers with intraprotein dielectric properties.
The local dielectric permittivity inferred from the electrometric measurements could be quantitatively used to estimate the rate constant of ET reactions in membrane proteins with resolved atomic structure with the accuracy of less than one order of magnitude. Expand

Dielectric and photoelectric properties of photosynthetic reaction centers
A simple kinetic model of the primary processes of electron transfer in photosynthesis is used to discuss possible mechanisms of correlation between rate constant of charge transfer reaction, free energy of electron transition, and effective dielectric constant in the locus of corresponding carriers.
