Research Abstract

Anesthetics ( Xe, Kr, Ar ) bound to (A) lipid binding site, (B) pre-filter water site, (C) inter-helix site, (D) C-terminal domain, and (E) gate. Xenon distributed to lipid binding site. This binding site is in between protein-water and lipid-water interfaces. Pre-filter water site is structured water site which involves dehydration process of potassium ion. These xenon binding site are suggested to have important contributions to modification of KcsA function.
