FUCA1, also known as tissue alpha-L-fucosidase, is responsible for hydrolyzing the alpha-1,6-linked fucose joined to the reducing-end N-acetylglucosamine of the carbohydrate moieties of glycoproteins. Fucosidosis is an autosomal recessive lysosomal storage disease resulting from absence of alpha-L-fucosidase activity. Source: Recombinant protein corresponding to aa28-466 from human FUCA1, fused to His-tag at C-terminal expressed in insect cell.
