VERIFY3D profile plots of diphtheria toxin (DT) in three forms: open and closed monomers and the dimer. (a) DT open monomer (dashed), DT dimer (solid line). (b) DT closed monomer (dashed) and dimer (solid line). Notice that the hinge loop (residues 379–387) in the open monomer has a low profile score, and this structure is known to be unstable. The score is raised in the stable closed monomer and in the dimer.
