REMARK 3 THE MODEL CONSISTS OF THE 137 AMINO ACID RESIDUE REMARK 3 CARBOHYDRATE RECOGNITION DOMAIN IN COMPLEX WITH REMARK 3 N-ACETYLLACTOSAMINE AND 120 WATER MOLECULES. REMARK 3 THIS STRUCTURE REPRESENTS A CRD DETERMINED FROM A GALECTIN REMARK 3 WHICH DOES NOT SHOW THE CANONICAL 2-FOLD SYMMETRIC DIMER REMARK 3 ORGANIZATION SHOWN BY GALECTINS-1 AND -2. COMPARISON WITH REMARK 3 GALECTINS-1 AND -2 PROVIDES AN EXPLANATION FOR THE REMARK 3 DIFFERENCES IN CARBOHYDRATE-BINDING SPECIFICITY SHOWN BY REMARK 3 GALECTIN-3, AND FOR THE FACT THAT IT FAILS TO FORM DIMERS REMARK 3 BY ANALOGOUS CRD-CRD INTERACTIONS.
