Nonstationary electric currents are described which are generated by the Na,K-pump. Flat membrane sheets 0.2–1 μm in diameter containing a high density of oriented N,K-ATPase molecules are bound to a planar lipid bilayer acting as a capacitive electrode. In the aqueous phase adjacent to the bound membrane sheets, ATP is released within milliseconds from an inactive, photolabile precursor (“caged” ATP) by an intense flash of light. After the ATP-concentration jump, transient current and voltage… CONTINUE READING
