iduronate-2-sulfatase. Iduronate 2-sulfatase is a sulfatase enzyme that catalyze the hydrolysis of sulfate ester bonds from a wide variety of substrates, including steroids, carbohydrates and proteins. Iduronate 2-sulfatase is required for the lysosomal degradation of heparan sulfate and dermatan sulfate. Mutations in the iduronate 2-sulfatase gene that result in enzymatic deficiency lead to the sex-linked mucopolysaccharidosis type II, also known as Hunter syndrome.

N-sulfoglucosamine sulfohydrolase (SGSH; sulfamidase). N-sulfoglucosamine sulfohydrolase (SGSH) belongs to the sulfatase family and catalyses the cleavage of N-linked sulfate groups from the GAGs heparin sulfate and heparin. The active site is characterized by the amino-acid sequence motif C(X)PSR that is highly conserved among most sulfatases. The cysteine residue is post-translationally converted to a formylglycine (FGly) residue, which is crucial for the catalytic process. Loss of function of SGSH results a disease called mucopolysaccharidosis type IIIA (Sanfilippo A syndrome), a fatal childhood-onset neurodegenerative disease with mild facial, visceral and skeletal abnormalities.

uncharacterized sulfatase subfamily. Sulfatases catalyze the hydrolysis of sulfate esters from wide range of substrates, including steroids, carbohydrates and proteins. Sulfate esters may be formed from various alcohols and amines. The biological roles of sulfatase includes the cycling of sulfur in the environment, in the degradation of sulfated glycosaminoglycans and glycolipids in the lysosome, and in remodeling sulfated glycosaminoglycans in the extracellular space. The sulfatases are essential for human metabolism. At least eight human monogenic diseases are caused by the deficiency of individual sulfatases.

unchracterized sulfatase homologous to glucosamine (N-acetyl)-6-sulfatase(G6S, GNS). N-acetylglucosamine-6-sulfatase also known as glucosamine (N-acetyl)-6-sulfatase hydrolyzes of the 6-sulfate groups of the N-acetyl-D-glucosamine 6-sulfate units of heparan sulfate and keratan sulfate. Deficiency of N-acetylglucosamine-6-sulfatase results in the disease of Sanfilippo Syndrome type IIId or Mucopolysaccharidosis III (MPS-III), a rare autosomal recessive lysosomal storage disease.
