Differential sensitivity of d-galactose-binding lectins from fruits of dwarf elder (Sambucus ebulus L.) to a simulated gastric fluid

► Dwarf elder fruit lectins share amino acid sequences of Sam n1 allergen. ► Sam n1 allergen features fits with the lectin SELlm from dwarf elder shoots. ► Intraperitoneal ebulin f is more toxic than oral at the same dose. ► Ebulin f is digested by pepsin while SELfd is not sensitive under the same conditions.
