Calcium ATPase of sarcoplasmic reticulum has four binding sites for calcium

The calcium-transporting ATPase of sarcoplasmic reticulum is known to bind two Ca2+ ions from the cytoplasm to the free enzyme and two Ca2+ ions from the lumen to the phosphoenzyme. The concentration of phosphoenzyme formed at equilibrium from Pi and Mg2+ increases with increasing concentration of c...
