X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	6.7	293	Crystals were formed by mixing in a 1:1 ratio the purified endonuclease protein (5 mg/ml) with crystallization buffer containing 200 mM MES pH 6.7, 27% PEG8000, 200 mM ammonium sulfate, 1 mM manganese chloride, 10 mM magnesium acetate, 10 mM taurine, and 50 mM sodium fluoride. Crystals matured to full size in one to two weeks at 20 degrees C.
