Side chain interactions protein structure

WebA major determinant is the interactions between side chains of the residues in the polypeptide. Several factors come into play: ... Some proteins are composed of more than one polypeptide chain. In such proteins, … WebEnzymes are protein molecules - long chains of amino acid residues. Remember that sticking out all along those chains are the side groups of the amino acids - the "R" groups that we talked about on the page about protein structure. Active sites, of course, have these "R" groups lining them as well - typically from about 3 to 12 in an active site.

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. Webβ-Sheets are quite frequent in protein structures and are stabilized by regular main-chain hydrogen bond patterns.
