精密化 | 構造決定の手法: MULTIPLE ISOMORPHOUS METHOD / 解像度: 2.1→5 Å / σ(F): 2 詳細: THE STRUCTURE WAS SOLVED BY THE MULTIPLE ISOMORPHOUS REPLACEMENT METHOD. THE MODEL CONSISTS OF THE 137 AMINO ACID RESIDUE CARBOHYDRATE RECOGNITION DOMAIN IN COMPLEX WITH N-ACETYLLACTOSAMINE ...詳細: THE STRUCTURE WAS SOLVED BY THE MULTIPLE ISOMORPHOUS REPLACEMENT METHOD. THE MODEL CONSISTS OF THE 137 AMINO ACID RESIDUE CARBOHYDRATE RECOGNITION DOMAIN IN COMPLEX WITH N-ACETYLLACTOSAMINE AND 120 WATER MOLECULES. THIS STRUCTURE REPRESENTS A CRD DETERMINED FROM A GALECTIN WHICH DOES NOT SHOW THE CANONICAL 2-FOLD SYMMETRIC DIMER ORGANIZATION SHOWN BY GALECTINS-1 AND -2. COMPARISON WITH GALECTINS-1 AND -2 PROVIDES AN EXPLANATION FOR THE DIFFERENCES IN CARBOHYDRATE-BINDING SPECIFICITY SHOWN BY GALECTIN-3, AND FOR THE FACT THAT IT FAILS TO FORM DIMERS BY ANALOGOUS CRD-CRD INTERACTIONS.
