were investigated comparatively. Oligosaccharides released from the two enzymes by hydrazinolysis were fractionated by paper electrophoresis, serial chromatographies on columns of immobilized Aleuria aurantia lectin, concanavalin A, phytohemagglutinin Ed,and Datura stramonium agglutinin, and Bio-Gel P-4 (
