It has been recently recognized that lectins exhibit other activities besides hemagglutination. Previously we have found that purified lectin from Chelidonium majus showed DNase activity (Fik, Gozdzicka-Jozefiak & Kedzia, 1995, Herba Polon. 41, 84-95). Comparison of lectin and DNase from the sap from leaves and roots of Chelidonium majus proved that both these compounds are composed of 24kDa monomer subunits which have an identical N-terminal sequence but differ in amino-acid composition and degree of glycosylation. Possible interrelationship between lectin and DNase is discussed.
