X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.0	?	Crystals of the HIS79ALA mutant were obtained by mixing the apoenzyme retaining the C-terminal HISs-tag (6.7 mg/ml, 20 mM DTT, 25 mM HEPES pH 6.8, 25 mM K2SO4, 100 mM NaCl) with an equal volume of well solution (22-27 % PEG 3400, 0.1 M HEPES pH 7.0, 200 mM NaCl). Diffraction quality crystals were obtained after macroseeding into 20 uL hanging drops.
