in order to study the mechanism for activation of atp hydrolysis by mg2+ , the stoichiometry of the high affinity calcium-binding sites with respect to each form of reaction intermediate of sarcoplasmic reticulum atpase was determined at 0 degrees c and ph 7.0 in the presence and absence of added mg2+ using the purified atpase preparation .
