|Fc| map of the ΔTGEE hinge regions
for all three molecules, Mol A, Mol B, and Mol C. The last helix (helix F)
of the FMN domain and the first β strand (β6) of the connecting/FAD
domain are depicted with thin lines, and the hinge sections are
depicted with thick lines. Maps are contoured at the 2.5 σ
level. Although side chains of some residues in the hinge regions are not
visible, the main chains of all three hinges are clearly defined.
