2.4.1.65	GDP-fucose + Gal-beta-1,4GlcNAc-beta-1-R	-	
2.4.1.65	GDP-L-fucose + 1,3-beta-D-galactosyl-N-acetyl-D-glucosaminyl-R	the enzyme catalyzes the synthesis of fucosylated Lewis motifs that are associated with cell-adhesion events and are differentially expressed during cell differentiation	
2.4.1.65	GDP-L-fucose + 1,3-beta-D-galactosyl-N-acetyl-D-glucosaminyl-R	inactivation of the enzyme eliminates expression of all Lewis antigens	
2.4.1.65	GDP-L-fucose + 1,3-beta-D-galactosyl-N-acetyl-D-glucosaminyl-R	the enzyme may catalyze alpha1-3 and alpha-1,4 glycosidic linkages involved in the expression of VIM-2, Lewis A, Lewis B, sialyl Lewis X and Lewis X/SSEA-1 antigens. May be involved in blood group Lewis determination. Lewis-positive individuals have an active enzyme while Lewis-negative individuals have an inactive enzyme	
2.4.1.65	GDP-L-fucose + 1,3-beta-D-galactosyl-N-acetyl-D-glucosaminyl-R	the enzyme may catalyze alpha-1,3 and alpha-1,4 glycosidic linkages involved in expression of sialyl Lewis X and Lewis X/SSEA-1 antigens. It may be involved in blood group Lewis determination	
2.4.1.65	GDP-L-fucose + Lewis antigen	on the cell surface of hepatocarcinoma cells H7721	
2.4.1.65	additional information	the enzyme is involved in the biosynthesis of the E-selectin ligand, sialyl-Lewis X. Catalyzes the transfer of fucose from GDP-beta-fucose to alpha-2,3 sialylated substrates	
2.4.1.65	additional information	the enzyme is involved in the biosynthesis of the sialyl Lewis x, i.e. Lex, epitope on leukocytes, which has been identified as an important component of leukocyte ligands for E- and P-selectin	
2.4.1.65	additional information	the strong correlation between the promoter activity of the FUT III gene and the high expression of sialyl Le(a) observed in different colon carcinoma cell lines seems to conform the important regulatory role of FUT3 in the synthesis of sialyl Le(a)
