α-L-fucosidase (EC 188.8.131.52)  is a lysosomal enzyme responsible for hydrolyzing the α-1,6-linked fucose joined to the reducing-end N-acetylglucosamine of the carbohydrate moieties of glycoproteins. Deficiency of α-L-fucosidase results in the lysosomal storage disease fucosidosis.
A cysteine residue is important for the activity of the enzyme. There is only one cysteine conserved between the sequence of mammalian α-L-fucosidase and that of the slime mold Dictyostelium discoideum. We have derived a pattern from the region around that conserved cysteine.Note:
