BRITE hierarchy
Sysname
2-alpha-L-fucopyranosyl-beta-D-galactoside fucohydrolase
Reaction(IUBMB)
methyl-2-alpha-L-fucopyranosyl-beta-D-galactoside + H2O = L-fucose + methyl beta-D-galactoside [RN:R04270 R06118]
Reaction(KEGG)
Substrate
methyl-2-alpha-L-fucopyranosyl-beta-D-galactoside [CPD:C04698];
H2O [CPD:C00001]
Product
L-fucose [CPD:C01019];
methyl beta-D-galactoside [CPD:C03619]
Comment
Highly specific for non-reducing terminal L-fucose residues linked to D-galactose residues by a 1,2-alpha-linkage. Not identical with EC 3.2.1.111 1,3-alpha-L-fucosidase.
