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)
