Abstract: A novel antiretroviral protein Polygonatum cyrtonema lectin (PCL) belonging to the monocot mannose-binding lectin (MMBL) superfamily has been crystallized using hanging-drop vapor-diffusion method. The crystals diffract to 2.0 Å resolution and belong to space group P21, with unit-cell parameters of a=39.308 Å, b=48.317 Å, c=112.221 Å, and β=90.12° . Preliminary analysis indicates that the asymmetric unit contains four PCL molecules with a solvent content of about 45%. A set of X-ray data has been collected for the crystal structure determination.
