1	VAPOR DIFFUSION, SITTING DROP		295	Crystals were grown in the presence of XMP and NAD+ in mother liquor from the condition 1-10 of the commercial screen Morpheus (Molecular Dimensions), which consists of a salt mixture (0.03M Magnesium chloride hexahydrate and 0.03M Calcium chloride dihydrate), a precipitant mix (20% v/v Ethylene glycol and 10 % w/v PEG 8000), and 0.1M of a buffer system (Tris-base, Bicine) adjusted at pH 8.5. Initial concentrations: Protein = 12.5 mg/mL XMP = 3 mM NAD = 3 mM
