Example 1:
An enzyme is a single chain of 300 residues. A Ramachandran plot of
main chain torsion angles shows that 88% of the residues are in most
favored (MF) regions, 9% are in additionally allowed (AA) regions, 2% in
generously allowed (GA), and 1% in disallowed (D) regions.
In this example, the Ramachandran plot is calculated over the main chain,
for which the sequence limits (referenced by the label 'HD') will be
found elsewhere in the file (in the PDBX_SEQUENCE_RANGE category).

are identifiers and qualifiers needed to preserve the mmCIF data structure,
and are auto-generated during the deposition procedure.
