X-RAY DIFFRACTION	?	296	Mutant S181A 20beta-HSDH purified recombinant protein was incubated with 2.5 mM NADH and 0.25mM or 0.5 mM cortisol for 2 hours at 4C. Crystals were grown in condition 86 of the Hampton PEG/Ion screen containing 0.05 M Citric acid, 0.05 M BIS-TRIS propane / pH 5.0, and 16% w/v Polyethylene glycol 3,350. The condition was then optimized in hanging-drop format using 18-20% w/v Polyethylene glycol 3,350
