N-glycan Degradation: Alpha 1, 2-L Fucosidase

Alpha 1,2-L Fucosidase specifically cleaves the alpha 1,2 fucoside bond, liberating L-fucose from 22-alpha-L-fucosyl lactose (Fuc alpha1-2 Gal beta1-4 Glc) and from porcine gastric mucin oligosaccharides. It also liberates L-fucose from N-acetyllactosamine-type bi-antennary sugar chains with alpha 1,6 fucoside bonds, but the rate of this reaction is extremely slow. Alpha 1,2-L Fucosidase can be used during N-glycan degradation.
