;THE ECHINOMYCIN IS A BICYCLIC OCTADEPSIPEPTIDE, A MEMBER
OF THE QUINOXALINE CLASS OF ANTIBIOTICS.
HERE, ECHINOMYCIN IS REPRESENTED BY GROUPING TOGETHER THE
SEQUENCE (SEQRES) AND TWO LIGANDS (HET) QUI.
;
_pdbx_reference_molecule.description                  
;ECHINOMYCIN IS A BICYCLIC OCTADEPSIPEPTIDE.
BICYCLIZATION IS ACHIEVED BY LINKING THE N- AND
THE C- TERMINI, AND A THIOACETAL BOND BETWEEN
RESIDUES 3 AND 7.
THE TWO QUINOXALINE CHROMOPHORES ARE LINKED
TO THE D-SERINE RESIDUES, RESIDUES 1 AND 5.
