Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 7.5 293 PEG 3350, POTASSIUM PHOSPHATE, Crystals of the complexes were obtained by standard vapor equilibration methods with conditions optimized by screens varying protein concentration, pH, drug molar ratios, centered on the original crystallization hit using protocols described previously for the monoclinic [Carter, et al., Eur. J. Biochemistry (1994) 226: 1049-1052] and triclinic [Sugo, et al., Protein Eng (1999) 12: 439-446] crystal forms., pH 7.5, VAPOR DIFFUSION, SITTING DROP, temperature 293K
