an alpha-L-fucoside + H2O = L-fucose + an alcohol
the enzyme catalyses the transfer of L-fucose from donor structures such as alpha-L FucpOpNP and alpha-L-FucpF to various GlcpNac derivates and glCP, forming alpha-(1-3)linkages
-
an alpha-L-fucoside + H2O = L-fucose + an alcohol
the enzyme cleaves alpha1-6-, alpha1-3-, alpha1-4- and alpha1-2-O-fucolsyl bonds in fucosylated oligosaccharides
