Purification and crystallization of a schistosomal glutathione S-Transferase

The 26-kDa glutathione S-transferase from Schistosoma japonica (Sj26), a potential antischistosomal vaccine antigen, has been crystallized in an unligated form. Sj26 was recombinantly produced in E. coli without using a glutathione affinity column to facilitate preparation of unligated enzyme. The recombinant protein contains all 218 residues of Sj26^1,2 and an additional 13 residues linked to the C-terminus. Crystals of recombinant Sj26 were obtained by the vapor diffusion method using ammonium sulfate as the precipitant at pH 5.6. The crystals belong to the hexagonal space group P6₃22 with unit cell dimensions a = b = 125.2 Å and c = 72.0 Å and contain one Sj26 monomer per asymmetric unit. A complete native diffraction data set has been obtained to 2.4 Å resolution. © 1995 Wiley-Liss, Inc.     

Crystallization and preliminary crystallographic study of human CksHs1: A cell cycle regulatory protein

The cell cycle regulatory protein CksHs1 has been crystallized in a form suitable for X-ray studies. CksHsl crystals were grown in the presence of vanadate, a phos-phatase inhibitor, but were also obtained with phosphate or tungstate as a cofactor. They belong to the hexagonal space group P6₁22 with unit cell dimensions: a=b=94 Å, c=131.6 Å, and γ =120. The crystals grown in the presence of vanadate diffract X-rays to at least 2.8 Å. Molecular replacement results from the homologous human CksHs2 structure reveal that a dimer forms the crystal habit, giving the unusual V_m value of 4.4 ų/Da or a solvent content of 72%. © 1995 Wiley-Liss, Inc.
