X-RAY DIFFRACTION	4.8	293	Crystallization trials were performed at 293 K using the hanging-drop method using a Qiagen EasyXtal 15-well plate. A 15 mg.mL CALB solution in 20mM Na(CH3COO) pH = 4.8 was incubated with a solution of paraoxon-ethyl (SIGMA catalog n. N12816) 30mM in water for one day. 1 uL of CALB solution was diluted with 1 uL of the precipitant solution, made of 200mM Na(CH3COO) pH = 4.8, 20% (w.v) PEG4000, and 15% (v.v) glyceryl tributyrate (SIGMA catalog n. T8626). The drop was equilibrated by vapor diffusion against 500 uL of the precipitant solution. Protein crystals of the CALB complex appeared within two weeks and grew to a size of 0.1 x 0.1 x 0.05 mm3 in five weeks.
