1 | VAPOR DIFFUSION, SITTING DROP | 6 | 289 | ACETYL COA SYNTHETASE FROM CRYPTOCOCCUS NEOFORMANS (CRNEC.00629.A.FS11.PD00402) AT 10MG/ ML (IN 10 MM TRIS, PH = 7.5, 20 MM NACL) WAS SET UP IN SPARSE CRYSTALLIZATION TRIALS AT 16C. 0.5MM AC-AMS WAS ADDED TO THE PROTEIN SOLUTION AND INCUBATED FOR 5 MINUTES BEFORE SETTING UP TRIALS. CRYSTALS WERE PRODUCED BY SITTING DROP VAPOR DIFFUSION WITH AN EQUAL VOLUME COMBINATION OF THE PROTEIN/LIGAND IN AN OPTIMIZATION SCREEN BASED ON WIZARD 1 AND 2 SCREEN CONDITION E8 (13.18% W/V PEG8,000, 0.2M NACL, 0.1M NA/K PHOSPHATE PH6) AND CRYO-PROTECTED IN 20% ETHYLENE GLYCOL. CRYSTAL ID 284335C8, ZNI9-6, APS21-ID-G), PH 6.0, VAPOR DIFFUSION, SITTING DROP, TEMPERATURE 289K |
