WebOct 6, 2024 · Van der waals interaction in proteins structure [edit edit source] In addition to hydrogen-bonds and disulfide bonds, protein structure can also be stabilized by Van der waals interactions. In the coiled-coil protein, there are Heptad repeat which form by the side chain interaction between each alpha helix; hepad-repeat is repeated in every 7th residues. WebThe results indicate that on average about 60 percent of aromatic side chains in proteins are involved in aromatic pairs, 80 percent of which form networks of three or more interacting aromatic side chains. Phenyl ring centroids are separated by a preferential distance of between 4.5 and 7 Å, and dihedral angles approaching 90° are most common.
