Crystallization and X-ray diffraction data for a new form of concanavalin A.
A new crystal form of concanavalin A, a well studied lectin from the jack bean (Canavalia ensiformis) is reported. These crystals, with the symmetry of orthorhombic space group C222(1), grow as large roughly equi-dimensional blocks. Unit-cell parameters at 120 K are a = 118.67 (12), b = 101.36 (13), c = 111.94 (9) A. On density considerations for two molecules per asymmetric unit, the water content is approximately 60%. Data to a nominal resolution of 1.5 A were collected.
