Substrate specificities
The glycoside hydrolases of this family are exo-acting α-fucosidases from archaeal, bacterial and eukaryotic origin. No other activities have been observed. The human enzyme is of medical interest because its deficiency leads to fucosidosis, a autosomal recessive lysosomal storage disease [1].
