Phosphatase

A group of enzymes which are important in the cycle of muscle contraction and in the calcification of bones.


An enzyme that catalyzes the removal of a phosphoryl group from a substrate.


Enzyme that acts as a catalyst in reactions involving phosphorus.


One of a group of enzymes capable of catalyzing the hydrolysis of phosphoric acid esters. An example is glucose-6-phosphatase, which catalyzes the hydrolysis of glucose-6-phosphate to glucose and phosphate. Phosphatases are important in the absorption and metabolism of carbohydrates, nucleotides, and phospholipids and are essential in the calcification of bone. Acid phosphatase is present in kidney, semen, serum, and the prostate gland. Alkaline phosphatase occurs in teeth, developing bone, plasma, kidney, and intestine.
