4-SULFATASE (HUMAN)
OverviewOverview
BACKGROUND:. Sulfatases catalyze the hydrolysis of sulfuric acid esters, from a wide variety of substrates including glycosaminoglycans, glycolipids and steroids. There is sufficient common sequence similarity, within the class of sulfatase enzymes to indicate that they have a common, structure. Deficiencies of specific lysosomal sulfatases that are involved, in the degradation of glycosamino-glycans lead to rare inherited clinical, disorders termed mucopolysaccharidoses. In sufferers of multiple sulfatase, deficiency, all sulfatases are inactive because an essential, post-translational modification of a specific active-site cysteine residue, to oxo-alanine does not occur. Studies of this disorder have contributed, to location and characterization of the sulfatase active site. To, ... [(full description)]
