Abstract

The glycosylation of glycoproteins from mammalian or plants can affect their efficacy, stability, solubility, and half-life. In the present study, we investigated plant glycosylation and their relative intensity (%) in a plant carbohydratebinding protein with the hemagglutination and antiproliferative activities. The hemagglutination activity on the deglycosylated protein was decreased as a 16-fold than that of intact glycoprotein. Using the HPLC with fluorescence detector and mass spectrometer, the major eight bi- or triantennary oligosaccharides containing xylose, fucose, mannose, galactose, and N-acetylglucosamine were identified and structurally characterized. The present results indicate that the oligosaccharides on this plant glycoprotein is necessary for their own property.
