Conditions initially obtained have been optimised using standard strategies, systematically varying parameters critically influencing crystallization, such as temperature, protein concentration, drop ratio, and others. These conditions were also refined by systematically varying pH or precipitant concentrations. Resolution 1.87 Å R-free 0.274
