Mapping the Protein Fold Universe Using the CamTube Force Field in Molecular Dynamics Simulations
Fig 6
Steric map in the CamTube model.
The map shows main steric restrictions (dashed black line) imposed by Hi-Hi+1, Oi–1-Oi and Oi–1-Ni+1 distances. Allowed regions are represented by light blue colour and they contain the range of dihedral angles present in right-handed α-helices, left-handed α-helices and β-sheets.
