功能： catalytic activity:Hydrolysis of terminal non-reducing N-acetyl-D-glucosamine residues in N-acetyl-alpha-D-glucosaminides.,caution:A MPS3B mutation at position 100 was erroneously reported (PubMed:9950362) as an amino acid change from Arg to His. The right amino acid change is from His to Arg.,disease:Defects in NAGLU are the cause of mucopolysaccharidosis type 3B (MPS3B) [MIM:252920]; also known as Sanfilippo syndrome B. MPS3B is a form of mucopolysaccharidosis type 3, an autosomal recessive lysosomal storage disease due to impaired degradation of heparan sulfate. MPS3 is characterized by severe central nervous system degeneration, but only mild somatic disease. Onset of clinical features usually occurs between 2 and 6 years; severe neurologic degeneration occurs in most patients between 6 and 10 years of age, and death occurs typically during the second or third decade of life.,function:Involved in the degradation of heparan sulfate.,subunit:Monomer and homodimer.,tissue specificity:Liver, ovary, peripheral blood leukocytes, testis, prostrate, spleen, colon, lung, placenta and kidney.,
