bis_protein_structure.residue_constants.load_stereo_chemical_props¶

bis_protein_structure.residue_constants.load_stereo_chemical_props() → Tuple[Mapping[str, List[Bond]], Mapping[str, List[Bond]], Mapping[str, List[BondAngle]]][source]¶

Load stereo_chemical_props.txt into a nice structure.

Load literature values for bond lengths and bond angles and translate bond angles into the length of the opposite edge of the triangle (“residue_virtual_bonds”).

Returns:: dict that maps resname –> list of Bond tuples residue_virtual_bonds: dict that maps resname –> list of Bond tuples residue_bond_angles: dict that maps resname –> list of BondAngle tuples
Return type:: residue_bonds
