In enzymology, an alpha-L-fucosidase (EC 3.2.1.51) is an enzyme that catalyzes the chemical reaction:an alpha-L-fucoside + H2O L-fucose + an alcohol. Thus, the two substrates of this enzyme are alpha-L-fucoside and H2O, whereas its two products are L-fucose and alcohol. This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O-and S-glycosyl compounds. This enzyme participates in n-glycan degradation and glycan structures-degradation.http://www.creative-enzymes.com/product/Native-Bovine-LFucosidase_1020.html
