The crystal structure of the murine Fab S-20-4 from a protective, anti-cholera Ab specific for the lipopolysaccharide Ag of the Ogawa, serotype has been determined in its unliganded form and in complex with, synthetic fragments of the Ogawa O-specific polysaccharide (O-SP). The, upstream terminal O-SP monosaccharide is shown to be the primary antigenic, determinant. Additional perosamine residues protrude outwards from the Ab, surface and contribute only marginally to the binding affinity and, specificity. A complementary water-excluding hydrophobic interface and, five Ab-Ag hydrogen bonds are crucial for carbohydrate recognition. The, structure reported here explains the serotype specificity of anti-Ogawa, Abs and provides a rational basis toward the development of a synthetic, carbohydrate-based anti-cholera vaccine.
