WebbFar-UV circular dichroism spectroscopy doesn't measure phi and psi angles of the backbone, it provides information on the secondary structure of the protein and measures the difference in absorption of left and right circularly polarized light and the resulting spectrum reflection. Determining the phi and psi angles requires X-ray crystallography. WebbThe Ramachandran plot depicts the statistical distribution of the backbone dihedral angle combinations and. In theory, the Ramachandran plot’s permissible regions illustrate which Phi/Psi angles are possible for an amino acid, X, in an ala-Xla tripeptide (Ramachandran et …
