1VAPOR DIFFUSION, HANGING DROP8.5CRYSTALS WERE GROWN AT ROOM TEMPERATURE BY HANGING-DROP VAPOR DIFFUSION AGAINST A WELL SOLUTION OF 22% (V/V) POLYETHYLENE GLYCOL WITH AN AVERAGE MOLECULAR WEIGHT OF 400 KDA (PEG 400), 0.15 M CACL2, 0.5% (V/V) MPD, 0.1 M TRISCL (PH 8.5). DROPS CONTAINED EQUAL VOLUMES (2 MICROL) OF WELL SOLUTION AND PURIFIED BENZOYLFORMATE DECARBOXYLASE [10 MG/ML IN 0.1 MM MGCL2, 0.2 MM TDP, 25 MM NAHEPES (PH 7.0)]., vapor diffusion - hanging drop
