S and r conformation
WebbConformations Let’s first talk about conformations. These, also referred to as conformers or conformational isomers, are different arrangements of atoms that occur as a result of rotation about single bonds. For example, in the following molecule, we can have a different arrangement of atoms by rotating around the middle σ bond: WebbAn analysis of the occurrence of i + 5-->i hydrogen bonded turn conformation at any general position in proteins (not specifically at the helix C-terminus), using coordinates of 228 protein crystal structures determined by X-ray crystallography to better than 2.5 A resolution is reported in this paper.
