ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6.5	290	CRYSTALLIZATION CONDITIONS: APO ENZYME CRYSTAL WAS OBTAINED AT 15 mg/ml, 13% PEG 8000, PH 6.5 IN SODIUM CACODYLATE BUFFER. THE APO ENZYME CRYSTAL WAS SOAKED IN CONCENTRATED INHIBITOR SOLUTION TO MAKE THE ENZYME/INHIBITOR COMPLEX CRYSTAL FOR X-RAY DATA COLLECTION, VAPOR DIFFUSION, HANGING DROP, temperature 290K
