Crystallization and Preliminary Crystallographic Study of 26kDa Clonorchis sinensis glutathione S-transferase Complexed with Inhibitors

A helminth glutathione S-transfease, 26 kDa isozyme from Clonorchis sinensis was cocrystallized with inhibitors by the hanging-drop method with monomethylether 550 as a precipitant. The crystals, grown in the presence of S-methylglutathione or trans-4-phenyl-3-buten-2-one, suitable for X-ray analysis, belong to the hexagonal space group P6₂(or P6₄), with unit cell parameters a= b= 97.6Å, c=117.4Å. X-ray diffraction data were collected with 2.5Å resolution.
