Abstract
Sugar specificity of the Machaerocereus eruca isolectins, MeAI and MeAII, has been determined by comparing the capacity of glycans with well defined structures to inhibit their haemagglutinating activity. Both are galactose-specific isolectins with high affinity for O-glycans. However, the two M. eruca isolectins recognize different oligosaccharidic sequences belonging to O-glycosidically linked glycans from porcine stomach mucin. The minimal structure recognized by MeAI on the porcine mucin glycans is the O-glycan core Gal beta 1,3GalNAc-ol, whereas MeAII has a more extended site and interacts with a biantennary O-glycan possessing the terminal trisaccharide Fuc alpha 1,2 (GalNAc alpha 1,3) Gal beta 1,4.Entities:
