Crystallization and preliminary X-ray diffraction studies of a pea lectin-methyl 3,6-di-O-(alpha-D-mannopyranosyl)-alpha-D-mannopyranoside complex.

The seed lectin isolated from garden peas (Pisum sativum) has been co-crystallized with methyl 3,6-di-O-(alpha-D-mannopyranosyl)-alpha-D-mannopyranoside in the orthorhombic space group P2(1)2(1)2(1) with unit cell dimensions a = 64.3 A, b = 73.4 A and C = 108.5 A. The asymmetric unit contains one pea lectin dimer (alpha 2 beta 2). The crystals are suitable for high-resolution structure analysis.
