This namespace contains constants for specifying Ramachandran data for different amino acid residue types.
The general residue type, meaning standard residues not captured by the below types.
The data used for the Glycine residues
The data used for the cis-Proline residues
The data used for the trans-Proline residues
The data used for a residue just prior to Proline in the protein chain, except Glycine, Isoleucine and Valine
The data used for Isoleucine and Valine residues
Unknown residue type, or the dihedral angles used to determine the type cannot be measured, e.g. for terminal residues.
