FIG 2.

Quaternary structures of the E. coli Dps dodecamer and ferritin 24-mers. (A) Ec-Dps dodecamer (PDB accession number 1DPS); (B) Ec-FtnA 24-mer (PDB accession number 1EUM); (C) Ec-Bfr 24-mer (PDB accession number 3E1J) (18, 180, 181). Monomer subunits are shown in distinct colors. Ec-FtnA is a partial structure; mirrored subunits are shown in the same color. Images are scaled to approximate size differences between the 90-Å-diameter Dps dodecamer and the 180-Å-diameter ferritin 24-mers. (Created with BioRender.com.)
