N-acetylglucosamine-6-sulfatase (EC 3.1.6.14, glucosamine (N-acetyl)-6-sulfatase, systematic name N-acetyl-D-glucosamine-6-sulfate 6-sulfohydrolase) is an enzyme that in humans is encoded by the GNS gene.[5] It is deficient in Sanfilippo Syndrome type IIId.[6][7][8] It catalyses the hydrolysis of the 6-sulfate groups of the N-acetyl-D-glucosamine 6-sulfate units of heparan sulfate and keratan sulfate
Function
N-acetylglucosamine-6-sulfatase is a lysosomal enzyme found in all cells. It is involved in the catabolism of heparin, heparan sulphate, and keratan sulphate.[5]
Clinical significance
Deficiency of this enzyme results in the accumulation of undergraded substrate and the lysosomal storage disorder mucopolysaccharidosis type IIID (Sanfilippo D syndrome). Mucopolysaccharidosis type IIID is the least common of the four subtypes of Sanfilippo syndrome.[5]
Nomenclature
The systematic name of this enzyme is "N-acetyl-D-glucosamine-6-sulfate 6-sulfohydrolase". Other accepted names include:
- N-acetylglucosamine-6-sulfatase,
- glucosamine (N-acetyl)-6-sulfatase,
- 2-acetamido-2-deoxy-D-glucose 6-sulfate sulfatase,
- N-acetylglucosamine 6-sulfate sulfatase,
- O,N-disulfate O-sulfohydrolase,
- acetylglucosamine 6-sulfatase,
- chondroitinsulfatase, and
- glucosamine-6-sulfatase.
