An ATPase is a group on enzymes in which ATP is hydrolyzed to ADP + Pi. ATPase is used in a large veriaty of cellular activities from the binding of DnaA to gene to amino acid degradation [1]. ATPase's are often used to pump ions across the cell membrane against their concentration gradient, know ions are that show this are H+, Na+, Cu2+, some also transport phospholipids with amino acid head groups[2].
The most commonly know ATPase is the sodium/potassium pump which actively transports three sodium ions out of the cell and two potassium ions into the cell for each ATP that it hydrolyzes setting up an electrochemical gradient [3]. Without this particular ATPase as with many others the body simply could not function correctly, thus ATPase's are extremely important enzymes within the cell.
