25 mM reduced the current. The dependence of the current on free Ca2+ was Michaelis-Menten-like, with half-maximal activation (KM(Ca)) at < 10 microM Ca2+. Caged Sr2+ and Ba2+, but not Mg2+, also supported photolysis-evoked outward current, as did Ni2+, but not Mn2+. However, Mg2+ and Mn2+ augmented the Ca-dependent current, perhaps by facilitating the adsorption of proteoliposomes to the BLM. The Ca-dependent current was irreversibly blocked by La3+ (added as 200 microM DMN-La3+). The results indicate that the properties of the Na/Ca exchanger can be studied with these electro-physiological methods." />
