    Abstract:
    Inorganic pyrophosphatase (PPase; EC 3.6.1.1) from the hyperthermophile Pyrococcus horikoshii was crystallized by the hanging-drop vapour-diffusion method at pH 5.0 using polyethyleneglycol 4000 as the precipitant. The crystal belongs to space group P2(1)2(1)2, with unit-cell parameters a = 71.7, b = 86.5, c = 92.5 A, alpha = beta = gamma = 90 degrees. There are two molecules in the asymmetric unit. The crystals were stable during exposure to X-rays and a full set of X-ray diffraction data was collected to 2.7 A resolution in-house.
