Functional Influence of the Pore Helix Glutamate in the KcsA K(+) Channel

The E71 residue is buried near the selectivity filter in the KcsA K(+) channel and forms a carboxyl-carboxylate bridge with D80. We have investigated the importance of E71 by examining neutralization mutants at this position using biochemical and electrophysiological methods. E71 mutations different...
