Crystals of an L-asparaginase from Vibrio succinogenes were obtained with the hanging drop method from ammonium sulphate-containing solutions. The crystals belong to the orthorhombic space group P22(1)2(1) with unit cell dimensions of a = 71.3 A, b = 85.8 A, c = 114.0 A, and contain two tetrameric enzyme molecules per unit cell. There are two subunits in the asymmetric unit; a molecular dyad is coincident with the crystallographic dyad. The crystal lattice is similar to that reported for an Escherichia coli asparaginase. Rotation function calculations have revealed that the V. succinogenes enzyme has 222 point group symmetry in the crystal. The second and third molecular dyads differ, however, from the corresponding E. coli asparaginase dyads by approximately 40 degrees. The crystals diffract to at least 2.2 A resolution and are suitable for X-ray crystallographic structure determination.
