Abstract
Alkaline phosphatases are enzymes that catalyze the hydrolysis ofphosphomonoesters, thus producing phosphate and alcohol. These enzymes are dimers insolution and are found in the great majority of organisms. In humans, four alkalinephosphatases have been identified so far. Three of them are tissue-nonspecific alkalinephosphatases (TNAP) and can be expressed in any tissue in the body. In m…
