Amino acid sequences for the α‐chains of the Moraceae lectins, jacalin and Maclura pomifera agglutinin, were determined by protein sequencing. Both are 133 residues long and contain several genetically variant positions; the overall homology is 85%. A possible site for the known glycopeptide ot jacalin was located. The α‐chains have a conserved tryptophan residue that may be part of the binding‐site.
