Human glutathione-S-transferase M2-2 (hGSTM2-2) was expressed in, Escherichia coli and purified by GSH-affinity chromatography. The, recombinant enzyme and the protein isolated from human tissue were, indistinguishable based on physicochemical, enzymatic and immunological, criteria. The catalytically active dimeric hGSTM2-2 was crystallized, without GSH or other active-site ligands in two crystal forms. Diffraction, from form A crystals extends to 2.5 A and is consistent with the space, group P21 (a = 53.9, b = 81.5, c = 55.6 A, beta = 109.26 A) with two, monomers in the asymmetric unit. Diffraction from form B crystals extends, to 3 A and is consistent with a space group P212121 (a = 57.2, b = 80.7, c, = 225.9 A) with two dimers in the asymmetric unit. This is the first, report of ligand-free mu-class GST crystals, and a comparison with, liganded complexes will provide insight into the structural consequences, of substrate binding which are thought to be important for catalysis.
