Artocarpus integrifolia (Jacalin) Lectin (AIA) – Pure

Jacalin lectin (AIA) is isolated from jackfruit seeds (Artocarpus integrifolia) and purified by affinity chromatography. AIA is a tetrameric two-chain structure consisting of four identical protomers and a molecular weight of 66, 000, with an isoelectric point of pH 7.8. The lectin has specificity for blood group types O (+SA) and T.Jacalin is considered a galactose-specific lectin and elutes with galactose or melibiose. A post-translational proteolytic modification of Jacalin gives the lectin a novel carbohydrate-binding site involving the N terminus of the -chain. The proteins structure explains its carbohydrate-binding specificity of T-antigen disaccharide Gal1, 3GalNAc. Potent inhibitors of jacalin include D-galactose, -Met-Gal and 2-deoxy–D-galactose.
