Crystallization and preliminary X-ray diffraction studies of a glutathione S-Transferase from the Australian sheep blowfly, Lucilia cuprina

Crystals of a glutathione S-transferase from the Australian sheep blowfly Lucilia cuprina have been grown from ammonium sulphate by the hanging drop vapour diffusion method. Successful crystallization required the presence of the inhibitor S-hexylglutathione. The crystals belong to the tetragonal space group P4₁122 or P4₃322) with cell dimensions of a = b = 88·1 A ̊ and c = 66·9 A ̊. They contain one monomer in the asymmetric unit and diffract beyond 2·8 Å resolution.
