Abstract

The role of long-range electrostatic forces in Porin OmpF channel conduction was investigated. A P3M force field scheme is self-consistently coupled with a Brownian dynamics (BD) kernel to study the role of long-range electrostatic forces in OmpF conduction. The P3M method is well suited to investigate electrostatic effects because it can account for the inhomogeneous, nonequilibrium behavior of the charge distribution. Within the computational domain, the atomic coordinates of the OmpF trimer are embedded in a uniform dielectric membrane. The results show that the inclusion of the long-range force leads to a lower potential as felt by the cation along the permeation pathway.
