Instead of using python to draw the diagram, there are also a selection of online tools to draw Ramachandran Plots for you, including: Ramachandran Server for structures deposited in the PDB , based on MOLEMAN2 by Gerard Kleywegt .
This server analyses the Ramachandran plot of a PDB file and compares it with the Ramachandran plots of about 400 representative structures solved at high resolution. Either Choose a pdb-file, Or Choose your own file
Ramachandran Plot. The 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.
Ramachandran Plot Generator. A Ramachandran plot is a graphical representation of the conformations of peptides and proteins based on the values of their phi and psi angles. Phi and psi are dihedral angles that describe the conformation of a protein's main chain.
PROCHECK checks the stereochemical quality of a protein structure, producing a number of PostScript plots analysing its overall and residue-by-residue geometry. It includes PROCHECK-NMR for checking the quality of structures solved by NMR.
