1,3-alpha-L-fucosidase

In enzymology, a 1,3-alpha-L-fucosidase () is an enzyme that catalyzes the chemical reaction of cleaving the 1,3-linkages between alpha-L-fucose and N-acetylglucosamine residues in glycoproteins.
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is 3-alpha-L-fucosyl-N-acetylglucosaminyl-glycoprotein fucohydrolase. This enzyme is also called almond emulsin fucosidase I. This enzyme participates in the degradation of glycan structures.
