Two Crystalline Forms of a Lectin from Flammulina veltipes

A lectin from Flammulina veltipes (Enoki-dake) has been crystallized in a form suitable for crystallographic structure analysis. Two types of crystals were grown: one from polyethylene glycol 6000 solution at pH 7 and the other from ammonium sulfate solution at pH 7. The latter type is more suitable for the crystallographic investigations because of its high resolution X-ray diffraction and smaller number of asymmetric molecules.
