Cat No.
NATE-0930
Description
This enzyme catalyses 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 GAGs, including dermatan sulfate and heparan sulfate. It is involved in the degeneration of glycosaminoglycans such as dermatan sulfate and heparan sulfate. It is found in the lysosomes of cells.
