Bovine serum conglutinin is a lectin which binds non-reducing terminal N-acetylglucosamine, mannose and fucose residues

Abstract
Carbohydrate recognition by bovine serum conglutinin has been investigaed 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.
