Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 7.5 294 Apo-enzyme was crystallized in the following conditions: a 4 uL drop of protein solution [10 mg/mL protein, 50 mM bicine (pH 8.5), 100 uM MnCl2] was mixed with a 4 uL drop of precipitant solution [25% PEG 3350, 0.1 M sodium acetate (pH 4.6)] on a siliconized cover slide and equilibrated against a 500 uL reservoir of precipitant solution. To obtain the Mn2+ bound form, apo-crystal was soaked in 10 mM MnCl2, 0.1 M sodium malonate (pH 7.5), 27% PEG 3350 for 24 hours, VAPOR DIFFUSION, SITTING DROP, temperature 294K
