Alpha-1,2-fucosyltransferase. Alpha-1,2-fucosyltransferases (Fut1, Fut2) catalyze the transfer of alpha-L-fucose to the terminal beta-D-galactose residue of glycoconjugates via an alpha-1,2-linkage, generating carbohydrate structures that exhibit H-antigenicity for blood-group carbohydrates. These structures also act as ligands for morphogenesis, the adhesion of microbes, and metastasizing cancer cells. Fut1 is responsible for producing the H antigen on red blood cells. Fut2 is expressed in epithelia of secretory tissues, and individuals termed "secretors" have at least one functional copy of the gene; they secrete H antigen which is further processed into A and/or B antigens depending on the ABO genotype. O-fucosyltransferase-like proteins are GDP-fucose dependent enzymes with similarities to the family 1 glycosyltransferases (GT1). They are soluble ER proteins that may be proteolytically cleaved from a membrane-associated preprotein, and are involved in the O-fucosylation of protein substrates, the core fucosylation of growth factor receptors, and other processes.

Glycosyltransferase family 6.

Glycosyltransferase family 6 comprises enzymes responsible for the production of the human ABO blood group antigens. Glycosyltransferase family 6, GT_6, comprises enzymes with three known activities: alpha-1,3-galactosyltransferase, alpha-1,3 N-acetylgalactosaminyltransferase, and alpha-galactosyltransferase. UDP-galactose:beta-galactosyl alpha-1,3-galactosyltransferase (alpha3GT) catalyzes the transfer of galactose from UDP-alpha-d-galactose into an alpha-1,3 linkage with beta-galactosyl groups in glycoconjugates. The enzyme exists in most mammalian species but is absent from humans, apes, and old world monkeys as a result of the mutational inactivation of the gene. The alpha-1,3 N-acetylgalactosaminyltransferase and alpha-galactosyltransferase are responsible for the production of the human ABO blood group antigens. A N-acetylgalactosaminyltransferases use a UDP-GalNAc donor to convert the H-antigen acceptor to the A antigen, whereas a galactosyltransferase uses a UDP-galactose donor to convert the H-antigen acceptor to the B antigen. Alpha-1,3 N-acetylgalactosaminyltransferase and alpha-galactosyltransferase differ only in the identity of four critical amino acid residues.

Glycosyl transferase family 11. This family contains several fucosyl transferase enzymes.

GDP-fucose protein O-fucosyltransferase and related proteins. O-fucosyltransferase-like proteins are GDP-fucose dependent enzymes with similarities to the family 1 glycosyltransferases (GT1). They are soluble ER proteins that may be proteolytically cleaved from a membrane-associated preprotein, and are involved in the O-fucosylation of protein substrates, the core fucosylation of growth factor receptors, and other processes.
