Plots of phi versus psi dihedral angles for amino acid residues are called Ramachandran plots.

Webb4 aug. 2016 · Secondary structure is characterized by the local rotational state of the protein backbone, quantified by two dihedral angles called ϕ and ψ. Particular types of secondary structure can generally be described by a single (diffuse) location on a two-dimensional plot drawn in the space of the angles ϕ and ψ, called a Ramachandran plot. WebbThis reasoning was the genesis of the Ramachandran plot.

WebbThe Ramachandran Plot We can vary ψ from –180˚ to 180˚ and we can vary φ from –180˚ to 180˚ (that is 360˚ of rotation for each). But many combinations of these angles are almost never seen and others are very, very common in proteins. Let us plot the values of ψ vs. the values of φ for an example globular protein. We will
