Electrostatics of photosynthetic reaction centers in membranes.

Abstract

Photosynthetic reaction centers are integral membrane complexes. They have potential application as molecular photovoltaic structures and have been used in diverse technological applications. A three-dimensional electrostatic model of the photosystem I reaction center (PSI) embedded in a lipid membrane is presented. The potential is obtained by solving the Poisson-Boltzmann equation with the finite element method (FEM). Simulations showing the potential distribution in a vesicle containing PSI reaction centers under different conditions are presented. The results of the simulations are compared with previous findings and a possible application of PSI to provide light activation of voltage-gated ion channels is discussed.
