摘要:
Saturation-transfer difference NMR spectroscopy (STD-NMR) experiments have been performed to analyze the topography or epitope of the octapeptide MDWNMHAA recognized by the anti-carbohydrate antibody SYA/J6 in solution; the antibody is directed against the Shigella flexneri Y O-antigen polysaccharide. The results permit a valuable comparison of solution versus crystal-structure data, and provide insight for the design of the next-generation binding ligands. (C) 2003 Elsevier Ltd.
