Alpha-L-fucosyltransferases in human submaxillary gland and stomach tissues associated with the H, Lea and Leb blood-group characters and ABH secretor status

• Schemes for the biosynthetic steps in the formation of the blood group active glycoproteins in secretions postulate that α-Image -fucosyltransferases specified by the Image and Image genes control the addition of Image -fucose to different acceptor sites in a precursor substance to give H, Lea and Leb serologically active structures. 1,2. The presence of 2-, 3- and 4-α-Image -fucosyl-transferases in submaxillary glands and stomach mucosal linings from persons who are secretors of ABH, and of 3- and 4-α-Image -fucosyltransferases in tissues from non-secretor persons, is described in this paper.
