Saturation transfer difference (STD) NMR spectroscopy was used to study the interaction of the lectin Vicia villosa (VVLB4) with alpha-D-GalNAc glycosylated beta(3)-peptides. The data were compared to those obtained with the monosaccharides D-Gal, D-GalNAc, and D-Glc as well as with those obtained with the Tn antigen alpha-glycopeptide (D-GalNAc-alpha-O-Ser/Thr), molecule naturally recognized by V. villosa. Evidence that the lectin also recognizes glycosylated beta(3)-peptides and has close contact with both the sugar and amino acid moieties was obtained. (C) 2009 Elsevier Ltd. All rights reserved.
