By making a Ramachandran plot, protein structural scientists can determine which torsional angles are permitted and can obtain insight into the structure of peptides.

2005-08-16 · Background The Ramachandran plot is a fundamental tool in the analysis of protein structures. Of the 4 basic types of Ramachandran plots, the interactions that determine the generic and proline Ramachandran plots are well understood. The interactions of the glycine and pre-proline Ramachandran plots are not. Results In glycine, the ψ angle is typically clustered at ψ = 180° and ψ = 0°. We

Sekar Department of Computational and Data Sciences Room No: 341, 2 nd Floor, Old CES Building Indian Institute of Science Introduction. The “Ramachandran plot” is an iconic image of modern biochemistry. In the late 1950s and early 1960s, Ramachandran and colleagues investigated the inter-atomic separations between nonbonded atoms in crystal structures of amino acids and related compounds. 1, 2 For different types of atom pairs, for example between C and C, C and O, and so on, they specified two sets of SAVES - Ramachandran Plot.

Residues in an alpha-helical conformation are marked α, and those in a beta strand conformation, β.The cluster of data in the upper right quadrant represents mostly turns. Ramachandran plots show the relationship between the phi and psi angles of a protein referring to dihedral angles between the N and the C-alpha and the C-alpha and the C-beta. As an aside, the omega angle between the C-beta and the N tends to be fixed due to pi-pi interactions.

RamachanDraw includes useful functions to effortlessly draw a Ramachandran plot. The Ramachandran Plot. In a polypeptide the main chain N-Calpha and Calpha-C bonds relatively are free to rotate. These rotations are represented by the torsion angles phi and psi, respectively. G N Ramachandran used computer models of small polypeptides to systematically vary phi and psi with the objective of finding stable conformations.

The model deriving from the SWISS-MODEL had energy and steric values raging between the values recorded for the other two mentioned strategies; therefore, the model resulting from MODELLER due to the adoption of the restriction method allowed the best steric evaluation results: 96.4% of the residues in favorable regions of the Ramachandran plot.

Ramachandran plot (RP) is the display of the (φ,) angle pairs of the polypeptide chain in a given protein structure in an easily comprehensible way (Ramachandran et al., 1963). Over the years, structural crystallographers and the protein modellers use the Ramachandran plot during ev-ery stage of model building to see whether the main chain
