“…Higher concentrations of the drug inhibited the enzyme activity. However, this effect was considered a non-specific interaction of the drug with this ATPase [15]. Other agents such as 30 mM Na ÷ and K ÷, 1 mM ouabain, 20 mM NAN3, 10 mM KCN and 0.1 mM dicyclohexylcarbodiimide had no effect on the high affinity Ca2÷-ATPase.…”
