WebbWhat is the difference between psi and phi angles? Amino acid residues in the beta-conformation have negative phi angles and the psi angles are positive. Typical values are phi = -140 degrees and psi = 130 degrees. In contrast, alpha-helical residues have both phi and psi negative. WebbThe angle of rotation (also called torsion angle or dihedral angle) around the N C α bond is called phi (φ) and that around the C α C bond is called psi (ψ) (Figure 8.1A).
