You can also visit the PDBSum web server at the EBI which has pre-calculated Ramachandran plots - simply enter the PDB codes for the four proteins of interest, or go to the links directly: 1HBS - an all-alpha protein, 3.00A resolution 2IG2 - an all-beta protein, 3.00A resolution 2PEG - an all-alpha protein, 1.48A resolution
This server will display a coloured Ramachandran plot. Blue means helix, red means strand and green means turn and loop (according to DSSP). The lines in the plot indicate the areas predicted by Ramachandran himself to be nergetically favourable. Either Choose a pdb-file, Or Choose your own file. If you have detected any error, or have any ...

Ramachandran and team also showed that the major effect of sidechains on the allowed phi and psi angles is due to C β 2. Sidechains larger than that of alanine affect the allowed angles by only a few percent 7, 8. The Ramachandran Plot below shows the phi and psi angles actually observed in proteins.
Supporting: 1, Mentioning: 80 - The Ramachandran plot displays the main chain conformation angles (Phi and Psi) of the polypeptide chain of a protein molecule. The paper reports the updated version of the Ramachandran plot web server and has several improved options for displaying the conformation angles in various regions. In addition, options are provided to display the conformation angles in various secondary structural elements and regions within the user specified Phi and Psi values in ...

The Ramachandran diagram plots phi versus psi dihedral angles for each residue in the input pdb file. The diagram is divided into favoured, allowed and disallowed regions, whose contouring is based on density dependent smoothing for 81234 non-Glycine, non-Proline and non-preProline residues with B < 30 from 500 high-resolution protein structures.
