  1. Ribbon representation of the Escherichia coli endonuclease III structure (PDB code 2ABK). Colour­codes: six­helix domain (residues 22-132) = deep red; helix­hairpin­helix (HhH) motif (108-130) = pink; four­helix domain, N­terminal helix (1-21) = light blue; four­helix domain, three C­terminal helices (133-211) = dark blue; [Fe4S4] cluster loop (187-203) = light green.
  2. [Fe4S4] cluster and its ligand Cys residues.
All drawings were produced by using the program MOLSCRIPT [2].
