The structures of sugar chains from Ricinus communis agglutinin were determined. Four glycopeptides were isolated from the lectin according to a published method (Kimura, Y. and Funatsu, G. (1988) Agric. Biol. Chem. 52, in press), and sugar chains of each glycopeptide were liberated by hydrazinolysis. Free amino groups were N-acetylated and the reducing-end residues were coupled with 2-aminopyridine. The resulting pyridylamino derivatives of sugar chains were purified by gel filtration and reversed-phase HPLC. The structures of thus-purified PA-sugar chains were determined by a combination of component analysis, stepwise exoglycosidase digestions, partial acetolysis, and 500 MHz 1H-NMR spectroscopy. These results indicate that R. communis agglutinin contains the sugar chains shown on page 249.
