Abstract:
Disproportionating enzyme (D-enzyme; EC 2.4.1.25) is a 59 kDa protein that belongs to the alpha-amylase family. D-enzyme catalyses intramolecular and intermolecular transglycosylation reactions of alpha-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 A resolution and belongs to space group C222(1), with unit-cell parameters a = 69.7, b = 120.3, c = 174.2 A.
