X-ray crystallization conditions BATCH MODE；310 K；The purified protein was used in crystallisation trials employing both, a standard screen with approximately 1200 different conditions, as well as crystallisation conditions identified using literature data. Condi- tions initially obtained have been optimised using standard strategies, systematically varying parameters critically influencing crystallisation, such as temperature, protein concentration, drop ratio, and others. These conditions were also refined by systematically varying pH or precipitant concentrations.
