The ramachandran plot
WebbG. N. Ramachandran, or GNR as he was known, one of the great Indian scientists of modern era.The Ramachandran plot has become a standard description of protein structures in the text books. His contributions in molecular biophysics, especially protein structure, were worthy of a Noble. WebbRamachandran plot for residues 5 to 10 of AdK, sampled from the AdK test trajectory (XTC). The contours in the background are the “allowed region” and the “marginally allowed” regions. The Janin class works in the same way, only needing a list of residues; see the Janin plot figure as an example.

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.
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 WebbThe Ramachandran Plot Window plots only values for the currently selected amino-acids of the current layer. The name of the current layer is drawn at the bottom left of the window. Amino-acids appear as a little cross with the exception of Gly that appears as a square.
