ATPase exists on the membrane of tissue cells and organelles. It is a kind of protease on the biological membrane which plays an important role in material transport, energy conversion and information transmission. The enzyme activity of ATPase will have a series of changes when the body in the hypoxic or diseases condition, and is also associated with some genetic diseases.
