Cartoon representations of the B. subtilis OxDC trimer and hexamer showing representative Mn–Mn distances. (A) Representation of the OxDC trimer showing distances between Mn ions in the same and adjacent OxDC monomers. Monomers are colored red, green, and purple, and the Mn ions are shown as purple (N-terminal domain) and yellow (C-terminal domain) spheres. (B) Representation of the OxDC hexamer showing the distance between the Mn ions (yellow spheres) in the layered OxDC trimers. One monomer is colored red to emphasize the role of α-helical regions in mediating monomer–monomer interactions.
