Alpha-L-fucosidase

In enzymology, an alpha-L-fucosidase is an enzyme that catalyzes the chemical reaction


 * an alpha-L-fucoside + H2O $$\rightleftharpoons$$ 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. The systematic name of this enzyme class is alpha-L-fucoside fucohydrolase. This enzyme is also called alpha-fucosidase. This enzyme participates in n-glycan degradation and glycan structures - degradation.
