An enzyme that hydrolyzes terminal desulfated α-l-iduronic acid residues of dermatan sulfate and of heparan sulfate; a deficiency of this enzyme is associated with Hurler syndrome and Scheie syndrome.


deficiency of the enzyme considered to be counterpart of mucopolysaccharidosis in cats and dogs; a neuronal storage disease.

Cord blood has been proposed as an alternative stem cell source for children with HS since it has been suggested that cord blood may increase their levels of lysosomal alpha-L-iduronidase, which consequently may allow them to live longer with fewer complications," said lead study author Jaap Jan Boelens, MD, PhD, of the University Medical Center Utrecht, in Utrecht, Netherlands.
