일반 설명
α-L-Iduronidase (IDUA) is mapped to human chromosome 4p16.3. The mature IDUA protein is glycosylated and comprises triosephosphate isomerase (TIM) barrel domain, β-sandwich, helix-loop-helix region and an immunoglobin-like domain. α-L-Iduronidase is classified under glycoside hydrolase (GH) family 39.
애플리케이션
α-L-Iduronidase may be used for leukocyte assay in the study of a-L-Iduronidase deficiency in new born.
생화학적/생리학적 작용
Catalyzes the hydrolysis of unsulfated α-L-iduronosidic linkages in dermatan sulfate
In lysosomal degradation process α-L-Iduronidase plays a crucial role. It hydrolyzes the non-reducing terminal α-L-iduronic acid residues in glycosaminoglycans (GAGs), including dermatan sulfate and heparan sulfate.
Mutation in the α-L-Iduronidase is implicated in Mucopolysaccharidosis I (MPS I) . This enzyme defect leades to accumulation of dermatan and heparan sulfate . MPS I pathophysiology is accompanied with deformation of the skull, mental retardation and hernias.

Mucopolysaccharidosis I (MPS I) is an autosomal recessive lysosomal storage disorder caused by a lack of the lysosomal enzyme α-L-iduronidase (IDUA). To date, more than 200 IDUA mutations have been reported. However, only a few types of mutations are recurrent
