UPR 5301

Centre de recherches sur les macromolécules végétales

Created in 1966 under the supervision of CNRS, the Centre de Recherches sur les Macromolecules Vegetales (CERMAV) is a fundamental research center devoted to Glycosciences, with strong and multidisciplinary expertise that spans from chemistry, physical-chemistry, biology to material sciences. It covers all the areas related to carbohydrates, their in vivo and in vitro synthesis, their characterization, and their functions and applications. Specifically, the main research area of CERMAV is devoted to the studies of saccharidic molecules: sugars, oligosaccharides and polysaccharides, glycoproteins and glycomaterials.

Visualisation of hydrogen atoms in a perdeuterated lectin-fucose complex reveals key details of protein-carbohydrate interactions

The pathogenic bacteria attach themselves to the cells which they attack thanks to the sugars present on their membrane. A crucial mechanism to study, because it would help to treat these infections without reinforcing the resistance of the bacteria. To do this, researchers from CERMAV (CNRS), the Laue-Langevin Institute (ILL) and CEITEC (Masaryk University, Czech Republic) have modified a sugar so that it responds to neutron crystallography, a technique that reveals how bacteria cling to sugars. This work, published in the journal Structure, could extend to more complex sugars to better understand different biological phenomena and propose new anti-infectious strategies. Caption: Fucose molecule in the lectin binding site. The blue grid represents the density determined by x-rays and the green grid the density determined by the neutrons around the fucose and the amino acids of the lectin. Hydrogen atoms (here isotope deuterium) are represented by yellow balls. The continuity of the green grid between the fucose and the amino acids allows a direct view of the hydrogen bonds. © L.
