X-RAY CRYSTALLOGRAPHY REVEALS CROSSLINKING OF MAMMALIAN LECTIN (GALECTIN-1) BY BIANTENNARY COMPLEX TYPE SACCHARIDESX-RAY CRYSTALLOGRAPHY REVEALS CROSSLINKING OF MAMMALIAN LECTIN (GALECTIN-1) BY BIANTENNARY COMPLEX TYPE SACCHARIDES
Structural highlights
FunctionLEG1_BOVIN May regulate apoptosis, cell proliferation and cell differentiation. Binds beta-galactoside and a wide array of complex carbohydrates. Inhibits CD45 protein phosphatase activity (By similarity). 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 PubMedGalectins are beta-galactoside-binding proteins that occur intra- and extracellularly in many animal tissues. They have been proposed to form networks of glycoconjugates on the cell surface, where they may modulate various cell response pathways such as growth, activation and adhesion. The high resolution X-ray crystallographic analyses of three crystal forms of bovine galectin-1 in complex with biantennary saccharides of N-acetyllactosamine type reveal infinite chains of lectin dimers cross-linked through N-acetyllactosamine units located at the end of the oligosaccharide antenna. The oligosaccharide adopts a different low energy conformation in each of the three crystal forms. Crosslinking of mammalian lectin (galectin-1) by complex biantennary saccharides.,Bourne Y, Bolgiano B, Liao DI, Strecker G, Cantau P, Herzberg O, Feizi T, Cambillau C Nat Struct Biol. 1994 Dec;1(12):863-70.
