Lectin that binds strongly to galactose, lactose, D-raffinose, L-rhamnose and cellobiose, and less strongly to D-glucose, D-xylose and L-arabinose. Does not bind D-galacturonic acid, D-fructose, D-mannose, D-ribose, L-sorbose, maltose and sucrose. Has hemagglutinating activity towards human type O and rabbit erythrocytes. Has strong antifungal activity against B.cinera with an IC(50) value of 1.2 uM, and weaker antifungal activity against D.turcia, F.oxysporum and Colletorichum sp. Lacks antifungal activity against F.oxysporum and M.arachidicola. Homodimer. Glycosylated. Hemagglutinating activity stable when incubated at 65 degrees Celsius for 30 minutes. Hemagglutinating activity is reduced by 50% when incubated at 75 degrees Celsius for 30 minutes and is abolished by incubation at 85 degrees Celsius for 30 minutes. Hemagglutinating activity is stable between pH 4.5 and 7.5, but is completely inhibited by incubation below pH 3.0 or above pH 10.
