Gougeon al, 1996a). A number of plant proteins such as the toxic lectins from Ricinus communis, Abrus precatorus,andViscum album Abstract have been identified that catalytically damage eukaryotic ribosomes making them unable to bind the elongation As reported previously by our group, among the toxic factor 2, and consequently unable to perform the elongation proteins from Viscum album L.
