1	VAPOR DIFFUSION, SITTING DROP	7.5	293	PEG 3350, POTASSIUM PHOSPHATE, PH 7.5, VAPOR DIFFUSION, SITTING DROP, TEMPERATURE 293K. 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.
