Exploring the Nature of Carbohydrate-Aromatic Dispersion Interactions via Sophisticated Computational Chemistry Tools
Popis výsledku v původním jazyce
There are several ways how saccharides interact with proteins. The role of dispersion-driven CH-pi interactions in protein-carbohydrate interactions has been underestimated for a long time. This type of interaction occurs between carbohydrate apolar faces and aromatic amino-acid residues. We introduce first systematic study of CH-pi interactions between selected carbohydrates and aromatic amino-acid models: benzene and naphtalene. 3D interaction energy (Eint) scan was performed to elucidate interactionenergy maps for carbohydrate-benzene interaction. Resulting most stable complexes were reoptimized and their Eint were refined at highly-sophisticated level. To study possible degree of additivity, we used geometries of carbohydrate-benzene complexes tobuild-up monodentate (interaction with one CH-group) and bidentate (interaction with two CH-groups) carbohydrate-naphtalene complexes. Also these complexes underwent the optimization and energy refinement procedure as described.
