Characterization Notes: The seeds of winged bean, Psophocarpus tetragonolobus(L.)DC, contain two distinct groups of lectins characterized by different erythrocyte hemagglutinating specificities and isoelectric points.
Biological Activity: The acidic lectins (PTA-I, PTA-II, PTA-II) agglutinated trypsinized human (type A, B, AB, and O) erythrocytes but not trypsinized rabbit erythrocytes.
Inhibitors: They were inhibited by various D-galactose derivatives and D-galactose-containing disaccharides and trisaccharides. N-Acetylgalactosamine was the best inhibitor, and the specificity appears to be directed to beta-D-galactosides. However, compared with w
