abstract = {We demonstrate that a combination of calculating the exact
electrostatic potential and approximate volume exclusion
within the sub-nanometer selectivity filter of a biological
ion channel is critical for estimating the selectivity of
the ion channel. Biological membranes separate solutions of
different ionic composition which can lead to significant
transmembrane voltages and chemical potentials. Ion
selective biological ion channels are used by nature to
manage these potentials. The high charge density within
these ion channels requires computation of the electrostatic
potential to consider induced charges on the dielectric
boundary between the aqueous solution and the
protein/membrane. Here, this is efficiently achieved by
constraining the dielectric boundary to be constant,
generating a set of surface elements, and pre-calculating a
set of simultaneous equations that provides the induced
charge of these elements in response to the external
electric field.},
