COVER<br />

Three dimensional structure of the molecular complex formed upon interaction of hevein, a plant lectin isolated from Hevea Brasiliensis tree,<br />

with the Manbeta1-4GlcNAcbeta14GlcNAcbetaAsn fragment of mammalian glycoproteins. The structure has been deduced by combination of<br />

NMR methods and molecular modelling protocols. The molecular recognition mode involves the typical interactions present in the recognition<br />

of neutral sugars by lectins, mainly CH-pi stacking interactions, hydrogen bonds and van der Waals forces. The figure has been designed by Dr.<br />

Ana Ardá and represents the first part of an ongoing collaboration with Prof. Carlo Unverzagt, at the University of Bayreuth, performed with the<br />

support of EUROCarbDB: http://www.eurocarbdb.org) and EU-NMR (http://www.eu-nmr.eu), and was presented at Tokyo during the XXV<br />

International Carbohydrate Symposium on the occasion of the Whistler Award to Jesús Jiménez-Barbero.<br />
