Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 7.8 281 Crystals were obtained at 4 C in 2 microlitre hanging drops with a 1:1 ratio of protein solution at 6 mg per ml in 20 mM HEPES, 300 mM NaCl, 2 mM tris(2-carboxyethyl)phosphine pH 7.8) to crystallisation solution. The crystallisation solution was 0.2 M lithium sulphate and 20% (w/v) PEG 3550.
