Stacking Interactions between Carbohydrate and Protein Quantified by Combination of Theoretical and Experimental Methods

Popis výsledku v původním jazyce

Carbohydrate - receptor interactions are an integral part of biological events. They play an important role in many cellular processes, such as cell-cell adhesion, cell differentiation and in-cell signaling. Carbohydrates can interact with a receptor byusing several types of intermolecular interactions. One of the most important is the interaction of a carbohydrate's apolar part with aromatic amino acid residues, known as dispersion interaction or CH/pi interaction. In the study presented here, we attempted for the first time to quantify how the CH/pi interaction contributes to a more general carbohydrate - protein interaction. We used a combined experimental approach, creating single and double point mutants with high level computational methods, andapplied both to Ralstonia solanacearum (RSL) lectin complexes with alpha-L-Me-fucoside. Experimentally measured binding affinities were compared with computed carbohydrate-aromatic amino acid residue interaction energies.
