Protein, at 15-17 mg/ml, was incubated with 10-fold molar excess of BXA for 30 min at RT, mixtures were centrifuged at RT for 5 minutes at 12000 g, and soluble fraction was used for crystallization trials (final protein concentration 8-10 mg/ml). Mother liquor was 0.2 M NaCl, 0.1 M Na(CH3)2AsO2 pH 6.5, 2 M (NH4)2SO4
