Hi all, Second post about symmetry, this time, we will focus on symmetry detection. This new App computes the axes of symmetry of biological assemblies. Here with 1CHP, just start the App and compute the symmetry:   For large assemblies, automatic symmetry detection may detect several different symmetries. Click on the one that is interesting (typically the one with the higher order and a small RMSD) to visualize the axis. In this example, we use 1B4B which has a dihedral…

PDB files often provide very interesting information on how proteins are organized in their crystal structure and biological assembly. Here we present a new SAMSON editor that will let you use this information in a few clicks. The so-called “Symmetry Mate Generator” element helps generate symmetric replicas of a protein based on the information contained in the pdb file. When this editor is selected, widgets appear. Use the mouse wheel to see more or fewer of these widgets. Here is an example…
