The relationship between the sign of the polypeptide backbone angle omega and the type of the side chain radical of amino-acid residues

Abstract

The dihedral angle ω, which reflects the nonplanarity of the peptide group, was found to be essential for describing the conformation of the polypeptide chain backbone in the context of particular side chain radicals of amino-acid residues. Conformational clusters corresponding to conformationally stable peptides identified previously were observed.
