Category CHEM_COMP_TOR

Name:
'chem_comp_tor'

Description:

   Data items in the CHEM_COMP_TOR category record details about
   the torsion angles in a chemical component. As torsion angles
   can have more than one target value, the target values are
   specified in the CHEM_COMP_TOR_VALUE category.

Example:

Example 1 - based on PDB entry 5HVP and laboratory records for the structure corresponding to PDB entry 5HVP.
