1	VAPOR DIFFUSION, SITTING DROP	8	293.15	Reservoir composition for crystal growth: 0.03M Magnesium chloride, 0.03 M calcium chloride, 0.05M imidazole, 0.05M MES, 10% v/v MPD, 10% w/v PEG 1000, 10% v/w PEG 3500P. Heavy atom derivatization: 1.2uL crystallization mother liquor containing 0.5mM KAu(CN)2 added to drop containing crystals. Drop size and composition: Sitting drops of 0.4ul were mixed in a protein:reservoir volume ratio of 1:1 using 45 mg/mL of OtCE15A in 20 mM TRIS pH 8.0
