1VAPOR DIFFUSION6.22890.2 ul of 12 mg/ml protein in 20 mM HEPES pH 7.5, 150 mM NaCl, 5% Glycerol, 10 mM BME, 5 mM NAD and 20 mM Tyrosine were mixed with 0.2 ul of the MCSG Suite 2 condition #81 (0.1 M Potassium/Sodium phosphate pH=6.2, 0.2M Sodium chloride, 20% w/v PEG 1000) and equilibrated against 1.5 M NaCl solution in 96 Well 3 drop Crystallization Plate (Swissci). Before crystallization the protein was incubated with 1/50 v/v of 2 mg/ml chymotrypsin solution at 289 K for 3 hours
