Parent Class:

EC-Numbers → 3 -- Hydrolases → 3.2 -- Glycosylases → 3.2.1 -- Glycosidases, i.e. enzymes hydrolyzing O- and S-glycosyl compounds

Synonyms: almond emulsin fucosidase, α-(1→2)-L-fucosidase

Systematic Name: 2-α-L-fucopyranosyl-β-D-galactoside fucohydrolase

Unification Links: BRENDA:3.2.1.63, ENZYME:3.2.1.63, IUBMB-ExplorEnz:3.2.1.63

Reaction:
methyl-2-α-L-fucopyranosyl-β-D-galactoside + H₂O → L-fucopyranose + methyl-β-D-galactoside

Summary:
Highly specific for non-reducing terminal L-fucose residues linked to D-galactose residues by a 1,2-α-linkage. Not identical with EC 3.2.1.111 1,3-α-L-fucosidase.
