Crystallization and preliminary X-ray analysis of the YjgF/YER057c/UK114-family protein ST0811 from Sulfolobus tokodaii strain 7

ST0811 from Sulfolobus tokodaii strain 7, a member of the YjgF/YER057c/UK114 protein family, was crystallized by the sitting-drop vapour-diffusion method using PEG 10 000 as precipitant. The crystals diffracted X-rays to beyond 2.0 Å resolution using an in-house rotating-anode generator. The crystals belonged to the rhombohedral space group R3, with hexagonal unit-cell parameters a = b = 55.0, c = 223.2 Å. The crystals contained two molecules in the asymmetric unit (V_M = 2.3 Å³ Da^-1) and had a solvent content of 47%.
