Ramachandran plot provides a simple two-dimensional graphic representation of all possible protein structures in terms of torsion angles. Although the plot was developed using theoretical methods,

Whether or not a Ramachandran plot is shown, phi (φ) and psi (ψ) are automatically assigned as residue attributes, and as such can be viewed/changed in the Selection Inspector or changed with setattr. 拉氏圖（又名 Ramachandran 圖、 [φ,ψ]圖、 α-碳與醯胺平面交角圖，英語： Ramachandran plot, Rama plot ），起初是於1963年由 G. N. Ramachandran，C. Ramakrishnan 和 V. Sasisekharan 提出的，是一種使蛋白質結構中，主鏈胺基酸殘基的二面角 ψ 和 φ 可視化的方法。. 左側的圖形說明了主鏈二面角φ 和 ψ 的定義（當時被Ramachandran叫做 φ 和 φ'）。. 肽鍵處的 ω 角通常是 180°，因為肽鍵的 Welcome to the Ramachandran server at Uppsala University .

Ramachandran Plot¶ To see where each residue lies in the Ramachandran Plot use the built in Ramachandran Plot tool: load the structure; Extras ‣ Analysis ‣ Ramachandran Plot. Molecule: 0 (or select your molecule) Selection: protein The Ramachandran Plot Explorer is designed to make it easy to examine the conformation of a polypeptide - through the interactive Ramachandran plot (φ-ψ angles) and χ-angle tool. Simply click on a residue, then drag the marker on the Ramachandran plot. The 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.

1. Ramachandran plot Description. The Ramachandran plot shows the phi-psi torsion angles for all residues in the ensemble (except those at the chain termini). Glycine residues are separately identified by triangles as these are not restricted to the regions of the plot appropriate to the other sidechain types. The Ramachandran Plot Window plots only values for the currently selected amino-acids of the current layer.

A plot that constitutes a map of all possible backbone configurations for an amino acid in a polypeptide. The axes of the plot consist of the rotation angles of the two backbone bonds that are free to rotate (φ and ψ, respectively); each point φ,ψ on the plot thus represents a conceivable amino acid …

The 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 …

The images below correspond to two different structures of the same protein. 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.

Furthermore, it can be noted that some of these conformations relate to specific secondary structures. As seen above, peptides in alpha-helices and beta-sheets adopt a even more limited set of phi-psi angles.
