The squid axon Na/Ca2+ exchanger shows ping pong kinetics only when the Ca2+(i)-regulatory site is saturated.

Abstract

In a previous work we demonstrated that, in dialyzed squid axons, an impairment of the Ca2+(i)-regulatory site affected the apparent affinities for external Na+ and Ca2+ in a way opposite to that predicted by the exiting (ping-pong) models for the exchangers. In the present work, we used model simulations and actual experiments where the Ca2+(i)-regulatory… (More)
