Control of ion flux and selectivity by negatively charged residues in the outer mouth of rat sodium channels.

1. The sodium channel has a ring of negatively charged amino acids on its external face. This common structural feature of cation-selective channels has been proposed to optimize conduction by electrostatic attraction of permeant cations into the channel mouth. We tested this idea by mutagenesis of...
