Carbohydrate recognition by bovine serum conglutinin has been investigated by inhibition and direct binding assays using glycoproteins and polysaccharides from Saccharomyces cerevisiae (baker's yeast), and neoglycolipids derived from N-acetylglucosamine oligomers, mannobiose and human milk oligosaccharides. The results clearly show that conglutinin is a lectin which binds terminal N-acetylglucosamine, mannose and fucose residues as found in chitobiose (GlcNAc beta 1-4GlcNAc), mannobiose (Man alpha 1-3Man) and lacto-N-fucopentaose II [Fuc alpha 1-4(Gal beta 1-3)GlcNAc beta 1-3Gal beta 1-4Glc] respectively.
