ATPases ( short form of adenosine triphosphatases ) are enzymes that can break down ATP into ADP and phosphate. In this hydrolysis releases energy that can be used by the enzyme to drive another reaction. Various ATPases as promote the transport of ions movement of muscle fibers or various reactions of energy metabolism. ATPases are found in all living things. Some ATPases are membrane proteins. These membrane-bound ATPases are shown in a separate article.

Other examples of ATPases are:

  • Sodium-potassium -ATPase
  • Dynein
  • Myosin
  • Phosphofructokinase
