Example text

One treatment is based on conformational energy calculations on proteins surrounded explicitly by solvent molecules. These calculations have thus far been aimed at determination of the intrinsic PKaS of specific groups on protein surfaces. In this approach (Russell and Warshel, 1985), the energy of dissociation of a particular acid group, AH, is computed for the whole protein surrounded by water molecules placed on a grid around the protein. D. Included in this energy is the effect of the permanent dipoles of the atoms of the protein that induce dipoles on the other atoms of the protein.

When only a very slight amount of potassium crosses the membrane (which for this example is assumed to be impermeable to chloride), the separation of charge creates a transmembrane electrical potential (Em) that is negative inside, relative to outside. The resultant electrical force retards further effiux of potassium. An equilibrium is reached when the diffusion force favoring effiux of potassium exactly balances the electrical force, preventing efflux of potassium. Prior to the attainment of equilibrium, the process of moving dn moles of K § ions out of the cell from compartment i to compartment o involves a change in free energy (dG) of the system.
