  1. Ribbon representation of the bacterioferritin dimer structure (PDB code 1BCF). Chain A = green; chain B = cyan.
  2. Haem and binuclear iron centres environment residues only. In each subunit, the two iron atoms are approximately octahedrally coordinated, with Ndelta ligands from His­54 and His­130, monodentate carboxylates from Glu­18 and Glu­94, and bridged by bidentate carboxylates from Glu­51 and Glu­127. The haem is bound symmetrically to subunits A and B by MetA­52 and MetB­52 residues.
All drawings were produced by using the program MOLSCRIPT [2].
