Dihedral angles in proteins and the Ramachandran plot

This in an index page pointing to several resources on these topics.

  • Definitions of phi and psi:
  • Simplified 3D models in JSmol that can be rotated with your mouse, and set to various dihedral angles: in English and Spanish.
  • Animated explanation identifying the 4 atoms for phi in a polypeptide, and rotating it clockwise (positive angles) and counter-clockwise (negative angles):
  • Dihedral angles in proteins: an interactive display of phi and psi dihedral angles using a model of a tripeptide.
    • A regular page in Proteopedia.
    • Simple presentation, featuring a 3D model with planes, clashes and animations.
  • Phi and Psi Angles: a more detailed, guided explanation of determination and display of angles in the 3D model.
    • A regular page in Proteopedia.
  • The Ramachandran Plot
    • A regular page in Proteopedia. Featured in an article in Biochemistry and Molecular Biology Education, 2010.
    • Extensive description with instructions on how to display the Ramachandran plot for any protein structure.
  • Ramachandran Plot Inspection
    • A special "Tutorial" page in Proteopedia (by Angel Herráez) and an equivalent page in Spanish
    • Interactive Ramachandran plot with many controls and details, connecting the Ramachandran plot with the display on the 3D model. Includes planes, clashes and animations.
    • You can display phi and psi for any pair of amino acids in any protein structure.

  • Another animation of phi and psi angles connected to a Ramachandran plot (by David Jollie)
  • Ramachandran outlier showcases a special case where a residue is not conforming to the favored values in the Ramachandran plot.
