Ion–peptide interactions between alkali metal ions and a termini-protected dipeptide: modeling a portion of the selectivity filter in K+ channels

Ion–peptide interactions between alkali metal ions and a termini-protected dipeptide: modeling a portion of the selectivity filter in K+ channels

S Ishiuchi, Y Sasaki, JM Lisy, M Fujii - Physical Chemistry Chemical …, 2019 - pubs.rsc.org

Potassium channels have the unique ability to allow the selective passage of potassium ions
at near diffusion-free rates while inhibiting the passage of more abundant sodium ions.
Local interactions between chemical functional groups and the ions are responsible for both …
