STRUCTURE OF A C-TYPE MANNOSE-BINDING PROTEIN COMPLEXED WITH AN OLIGOSACCHARIDE
Overview
C-type (Ca(2+)-dependent) animal lectins such as mannose-binding proteins, mediate many cell-surface carbohydrate-recognition events. The crystal, structure at 1.7 A resolution of the carbohydrate-recognition domain of, rat mannose-binding protein complexed with an oligomannose, asparaginyl-oligosaccharide reveals that Ca2+ forms coordination bonds, with the carbohydrate ligand. Carbohydrate specificity is determined by a, network of coordination and hydrogen bonds that stabilizes the ternary, complex of protein, Ca2+ and sugar. Two branches of the oligosaccharide, crosslink neighbouring carbohydrate-recognition domains in the crystal, enabling multivalent binding to a single oligosaccharide chain to be, visualized directly.
