    Abstract:
    A multiparticle computer model of plastocyanin-cytochrome f complex formation in the thylakoid lumen has been designed, which takes electrostatic interactions of proteins and the thylakoid membrane into account. The Poisson-Boltzmann formalism was used to determine the electrostatic potential field generated by the electrical charges of the proteins and the thylakoid membrane for different ionic strength values. The role of electrostatic field of the thylakoid membrane in plastocyanin-cytochrome f complex formation was determined. Using the model, the rate constant of plastocyanin-cytochrome f reaction for different values of ionic strength and membrane surface charge were calculated.
