phosphatase

A phosphatase is an enzyme that speeds up the removal of phosphate groups from organic compounds, a process called dephosphorylation. This is the opposite action of a kinase, which adds phosphate groups. Phosphatases are essential for many cellular processes, including muscle metabolism and bone formation.123456

There are different types of phosphatases, such as alkaline phosphatase and acid phosphatase. A deficiency in alkaline phosphatase can lead to a rare hereditary disorder called hypophosphatasia, which causes bone deformities. The reversible action of kinases and phosphatases on proteins is a key part of cell signaling.1564
