Webb12 mars 2024 · Torsion Angles [edit edit source] The two torsion angles of the polypeptide chain, also called Ramachandran angles, describe the rotations of the polypeptide backbone around the bonds between N-Cα (called Phi, φ) and Cα-C (called Psi, ψ). The Ramachandran plot provides an easy way to view the distribution of torsion … WebbBackbone angles in a protein are dihedral angles, which are the angles between two intersecting planes. They're also referred to as torsion angles, referring to how part of the backbone rotates or twists twists with regard to another part. The most important backbone angles are phi (φ) and psi (ψ). These angles are plotted on the Rama map.
