Abstract:
- The purification o f a soluble ATPase from beef heart mitochondria is described. The activity is dependent on Mg++ and is stimulated by 2,4-dinitrophenol. The enzyme cleaves the terminal phosphate of ATP and is inhibited by ADP. The activity is therefore assayed in the presence of an ATP regenerating system.
- The enzyme is cold labile. Although stable at room temperature, the enzyme rapidly loses activity at 4Ā°. ATP, which protects the enzyme against inactivation by heat and dialysis, does not prevent the cold inactivation.
- Attempts to demonstrate an exchange between either Pi32 or C14-ADP and ATP in the presence of the enzyme were unsuccessful.
- The properties of the purified enzyme are discussed in relation to particulate mitochondrial ATPase and to myosin ATPase.
