LITERATURE
hanging drop vapour diffusion method using 0.1 M BisTris pH 6.5 and 20% polyethylene glycol 5000 monomethylether
diffraction-quality crystals of salicylate 1,2-dioxygenase are obtained using the sitting-drop vapour-diffusion method at 4°C from a solution containing 10%(w/v) ethanol, 6%(w/v) PEG 400, 0.1 M sodium acetate pH 4.6. Crystals belong to the primitive tetragonal space group P4(3)2(1)2 or P4(1)2(1)2, with unit-cell parameters a = 133.3, c = 191.51 A

purified G106A enzyme mutant free and complexes with gentisate and salicylate, crystallization under anaerobic conditions, sitting drop vapor diffusion method, mixing of 0.001 ml of protein solution with 0.0008 ml of 8% poly(ethylene glycol)10000 and 0.1 M Tris/HCl pH 8.0, and 0.0002 ml of 0.1 M calcium chloride, crystal quality is improved using the seeding technique, X-ray diffraction structure determination and analysis at 2.0-2.58 A resolution
-
crystal structure at 2.8 A resolution, hanging drop vapor diffusion crystallization at 16°C. The crystal form belongs to the R32 space group, with two protein molecules (named as A and B) per asymmetric unit and 45% solvent content
