Hevein, a lectin-like protein is the major protein of vacuolar structures called lutoids in the latex of rubber trees. We have shown both by in planta and ex planta studies that hevein is involved in the coagulation of latex by bringing together rubber particles. This polyvalent bridging between hevein and rubber particles is mediated by N-acetyl-D-glucosamine and involves a receptor glycoprotein of 22 kDa, whichis localized on the surface of the rubber particles. The proposed role of hevein helps us to understand the mechanism of coagulation of latex and assigns a physiological intracellular function to one of the smallest lectins.
