# OERamaType¶

This namespace contains constants for specifying Ramachandran data for different amino acid residue types.

Note

The hierarchy used to determine the residue type is: Glycine > Isoleucine/Valine > pre-Proline > Cis/Trans Proline > General, as defined by [Vincent-2010].

General

The general residue type, meaning standard residues not captured by the below types.

Glycine

The data used for the Glycine residues

CisPro

The data used for the cis-Proline residues

TransPro

The data used for the trans-Proline residues

PrePro

The data used for a residue just prior to Proline in the protein chain, except Glycine, Isoleucine and Valine

IleVal

The data used for Isoleucine and Valine residues

Unknown

Unknown residue type, or the dihedral angles used to determine the type cannot be measured, e.g. for terminal residues.
