Popis: |
Ca2+ ions cause marked inhibition of (Na+ + K+)-ATPase. Strontium and barium ions exert a less pronounced inhibition of (Na+ + K+)-ATPase activity. These findings suggest the existence of a regulatory binding site for calcium ions on the (Na+ + K+)-ATPase molecule. Under physiological conditions, this binding site is presumably involved in stopping the activity of (Na+ + K+)-ATPase during depolarization of the sarcolemma. In pathological conditions which are characterized by calcium overload of cardiomyocytes inhibition of (Na+ + K+)-ATPase by calcium ions can significantly contribute to massive damage of myocardial cells. (Fig. 3, Ref. 26.). |
