The Ramachandran Plot • Disallowed regions generally involve steric hindrance between the side chain C-beta methylene group and main chain atoms Glycine has no side chain and therefore can adopt phi and psi angles in all four quadrants of the Ramachandran plot Hence it frequently occurs in turn regions of proteins where any other residue would be sterically hindered

Functionally relevant residues may occasionally have torsion angles that plot to the disallowed regions of a Ramachandran plot. The specific geometry of these functionally relevant residues, while energetically unfavorable, may be important for the protein’s function, catalytic or otherwise.

Glycine has no side chain and therefore can adopt phi and psi angles in all four quadrants of the Ramachandran plot. Hence it frequently occurs in turn regions of proteins where any other residue would be sterically hindered. Abstract. An analysis of the occurrence of nonglycyl residues in conformations disallowed in the Ramachandran plot is presented. Ser, Asn, Thr, and Cys have the highest propensities to exhibit such conformations, and the branched aliphatic residues the lowest.

The horizontal axis on the plot shows φ values, while the vertical shows ψ values. Both horizontal and vertical axes start from -180 and extend to +180. The images also show that φ and ψ angles of α-he The Ramachandran plot visualizes energetically allowed and forbidden regions for the dihedral angles. For poor quality homology models, many dihedral angles are found in the forbidden regions of the Ramachandran plot. Such deviations usually indicate problems with the structure.

However, it is showing an error on Procheck with Ramachandran plot with 0.7% of residues in the disallowed region. How should I optimize the model in order to get a proper Ramachandran plot for it of structural limitations and a detailed overview of the regions in the set of possible amino acid configurations that are allowed and disallowed.

How should I optimize the model in order to get a proper Ramachandran plot for it of structural limitations and a detailed overview of the regions in the set of possible amino acid configurations that are allowed and disallowed. This set of values is often graphically represented as a Ramachandran diagram.
