Abstract:
:A three-dimensional model of curculin, a sweet-tasting and taste-modifying protein from the fruits of Curculigo latifolia, was built from the X-ray coordinates of GNA, a mannose-binding lectin from snowdrop (Galanthus nivalis). The three mannose-binding sites present in GNA were found in curculin but are devoid of mannose-binding activity as shown by docking experiments performed with mannose. Some regions well exposed on the surface of the three-dimensional model of curculin could act as epitopes responsible for the sweet-tasting properties of this protein.
