Example 2:
A nuclear hormone receptor ligand-binding domain is a heterodimer
composed of two chains of homologous, but different sequences. For the
A monomer, the Ramachandran plot percentages are, for FA, AA, GA and D
regions, 77, 11, 8 and 4%, respectively, while for the X monomer,
they are 82, 13, 3 and 2%, respectively.
In this example, the Ramachandran plot is calculated separately
over the two monomers, for which the sequence limits (referenced by the
labels 'A' and 'X' respectively) will be found elsewhere in the file
(in the PDBX_SEQUENCE_RANGE category).
