摘要：

A multiparticle computer model of plastocyanin-cytochrome f complex formation in the thylakoid lumen has been designed, which takes into account the electrostatic interactions of proteins and membrane. The Poisson-Boltzmann formalism was used to determine the electrostatic potentials of the electron carrier proteins and the thylakoid membrane at different ionic strengths. The membrane electrostatic field was shown to influence plastocyanin diffusion and interaction with cytochrome f. The rate constants for plastocyanin-cytochrome f complex formation were calculated as a function of ionic strength and membrane surface charge. © 2010 Pleiades Publishing, Ltd.
