Arylsulfatase A/ARSA: Proteins and Enzymes

Sulfatases belong to a highly conserved family of enzymes that catalyze the hydrolysis of O- and N-sulfate esters from a variety of substrates. Among 18 human sulfatase genes identified, about 1/3 are found in lysosomes and serve to remove sulfate from glycosaminoglycans (GAGs), glycopeptides and glycolipids (GLs). The remaining sulfatases are found in microsomes, endoplasmic reticulum (ER), Golgi, at the cell surface, or secreted and are active against hydroxysteroids, heparin or unidentified ...
