2.4.1.69 additional information secretor-type alpha1-2 fucosyltransferase shows significant lower affinity than the H-gene encoded enzyme for phenyl-beta-D-galactopyranoside and GDP-L-fucose as well as for type 1 oligosaccharide acceptors, Galbeta1-4GlcNAc. Type 1 acceptors, Galbeta1-3GlcNAc, and type 3 acceptors, Galbeta1-3GalNAc, are preferentially used by the secretor-type enzyme as compared with the H enzyme Homo sapiens ?
