Kinetic effects of Ca2+ and Mg2+ on ATP hydrolysis by the purified ATP diphosphohydrolase

ATP diphosphohydrolase (EC 3.6.1.5) catalyzes the hydrolysis of diphospho- and triphosphonucleosides and is sensitive to divalent cations. In this paper, we investigated the dependence of ATP hydrolysis on the concentration of free Mg2+ and Ca2+ and the cation ATP complexes. The enzyme was isolated...
