Divalent cations and the activation kinetics of potassium channels in squid giant axons
The effects of external Zn+2 and other divalent cations on K channels in squid giant axons were studied. At low concentration (2 mM) Zn+2 slows opening kinetics without affecting closing kinetics. Higher concentrations (5-40 mM) progressively slow opening and speed channel closing to a lesser degree...
