STUDY OF THE CARBOHYDRATE CH/pi INTERACTIONS FAVOURABLE REGIONS IN THE CARBOHYDRATE SURROUNDINGS
Original language description
Molecular recognition of carbohydrates by proteins plays a key role in many biological processes including immune response, pathogen entry into a cell, cell-cell adhesion and so forth1-5. Recent studies show that key role in protein - saccharide recognition may play dispersive interactions, such as CH/pi interactions of aromatic amino acids with non polar faces of carbohydrates. In this study we present the first systematic computational three-dimensional scan of carbohydrate hydrophobic patches for theability to interact via CH/pi dispersion interactions. The carbohydrates b-D-glucopyranose, b-D-mannopyranose and a-L-fucopyranose were studied in a complex with a benzene molecule, which served as a model of the CH/pi interaction in carbohydrate/protein complexes. The 3D relaxed scans were performed at the SCC-DFTB-D level with 3 757 grid points for both carbohydrate hydrophobic sides. The interaction energy of all grid points was recalculated at the DFT-D BP/def2-TZVPP level.
