| Abstract: | Well-ordered single crystals have been grown for a mannose-specific lectin from snowdrop (Galanthus nivalis) bulbs in the presence of methyl-alpha-D-mannoside. The space group symmetry is consistent with the orthorhombic space group P2(1)2(1)2(1). The unit cell parameters are a = 140.0 A, b = 64.7 A, c = 62.0 A. The asymmetric unit can accommodate a tetramer. The functional molecule (50,000 daltons) consists of four identical subunits and is highly specific for alpha 1,3-linked mannose oligosaccharides. |
