CRYSTAL STRUCTURE OF HUMAN GALECTIN-7 IN COMPLEX WITH GALACTOSECRYSTAL STRUCTURE OF HUMAN GALECTIN-7 IN COMPLEX WITH GALACTOSE
Structural highlights
Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedKnowledge about carbohydrate recognition domains of galectins, formerly known as S-type animal lectins, is important in understanding their role(s) in cell-cell interactions. Here we report the crystal structure of human galectin-7 (hGal-7), in free form and in the presence of galactose, galactosamine, lactose, and N-acetyl-lactosamine at high resolution. This is the first structure of a galectin determined in both free and carbohydrate-bound forms. The structure shows a fold similar to that of the prototype galectins -1 and -2, but has greater similarity to a related galectin molecule, Gal-10. Even though the carbohydrate-binding residues are conserved, there are significant changes in this pocket due to shortening of a loop structure. The monomeric hGal-7 molecule exists as a dimer in the crystals, but adopts a packing arrangement considerably different from that of Gal-1 and Gal-2, which has implications for carbohydrate recognition. Structural basis for the recognition of carbohydrates by human galectin-7.,Leonidas DD, Vatzaki EH, Vorum H, Celis JE, Madsen P, Acharya KR Biochemistry. 1998 Oct 6;37(40):13930-40.
