Iduronat- 2- sulfatase virker ved at katabolisere glykosaminglykanerne (GAG) dermatansulfat og heparansulfat ved spaltning af oligosaccharid - forbundne sulfatdele.
Iduronate-2-sulfatase functions to catabolize the glycosaminoglycans (GAG) dermatan sulfate and heparan sulfate by cleavage of oligosaccharide-linked sulfate moieties.
