Summary

Description
English: Close-up sideview of a "stick" model of a pi helix of poly-alanine using the dihedral angles φ=-55° and ψ=-70° and the Engh&Huber bond geometry. Two hydrogen bonds are highlighted in magenta; the O-H distance is 1.65 Å (165 pm). The PDB file was made by me on 18 October 2006 using my own software and visualized by me using MOLMOL. I release this image under the GFDL.
