130-465 0e+00

Alpha-N-acetylglucosaminidase (NAGLU) tim-barrel domain; Alpha-N-acetylglucosaminidase, a lysosomal enzyme required for the stepwise degradation of heparan sulfate. Mutations on the alpha-N-acetylglucosaminidase (NAGLU) gene can lead to Mucopolysaccharidosis type IIIB (MPS IIIB; or Sanfilippo syndrome type B) characterized by neurological dysfunction but relatively mild somatic manifestations. The structure shows that the enzyme is composed of three domains. This central domain has a tim barrel fold.

Alpha-N-acetylglucosaminidase (NAGLU) N-terminal domain; Alpha-N-acetylglucosaminidase, a lysosomal enzyme required for the stepwise degradation of heparan sulfate. Mutations on the alpha-N-acetylglucosaminidase (NAGLU) gene can lead to Mucopolysaccharidosis type IIIB (MPS IIIB; or Sanfilippo syndrome type B) characterized by neurological dysfunction but relatively mild somatic manifestations. The structure shows that the enzyme is composed of three domains. This N-terminal domain has an alpha-beta fold.
