Disproportionating enzyme from potato was crystallized and preliminarily analyzed using X-ray diffraction. Disproportionating enzyme (D-enzyme; EC 2.4.1.25) is a 59 kDa protein that belongs to the α-amylase family. D-enzyme catalyses intramolecular and intermolecular transglycosylation reactions of α-1,4 glucan. A crystal of the D-enzyme from potato was obtained by the hanging-drop vapour-diffusion method. Preliminary X-ray data showed that the crystal diffracts to 2.0 Å resolution and belongs to space group C222{sub 1}, with unit-cell parameters a = 69.7, b = 120.3, c = 174.2 Å.
