| chondro-4-sulfatase | <enzyme> An arylsulfatase that catalyses the hydrolysis of the 4-sulfate groups of the disaccharide repeating units from chondroitin sulfate n-acetylgalactosamine 4-sulfate. The deficiency of chondro-4-sulfatase has been proposed as the defect in maroteaux-lamy syndrome (mucopolysaccharidosis vi). Chemical name: 4-Deoxy-beta-D-gluc-4-enuronosyl-(1,3)-N-acetyl-D-galactosamine-4-sulfate 4-sulfohydrolase Registry number: EC 3.1.6.9 (12 Dec 1998) |
