Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6.5	294	Crystals were grown in 25 % PEG 3350, 0.1 M Bis-Tris, pH 6.5, 0.2 M (NH4)2SO4 for TPNOX at 21 oC. Crystals were briefly soaked for 1-3 min in the formulation with 15 % (v/v) of ethylene glycol supplemented with 20-30 mM NADPH and were quickly frozen in liquid nitrogen.
