Bark lectins from the elderberry plants belonging to the genus Sambucus specifically bind to Neu5Acalpha2,6Gal/GalNAc sequence and have long been used for the analysis of sialoglycoconjugates that play important roles in many biological phenomena. However, molecular basis of such a unique carbohydrate binding specificity has not been understood. To answer these questions, we tried to identify the amino-acid residues in the Japanese elderberry bark lectin, Sambucus sieboldiana agglutinin that… Expand
