Figure 2
Overall structure of E. coli bacterioferritin. (a) Cartoon representation of the eight subunits found in the asymmetric unit. Additional subunits generating the entire protein shell are indicated as traces. (b) The bacterioferritin dimeric building block, consisting of two four-helix bundles. The short capping helices, which are involved in intersubunit contacts, are rendered in a different colour. The haem group is in stick representation and spheres indicate the metal positions of the ferroxidase centre. Figs. 2[link] and 3[link] were generated with PyMOL (DeLano Scientific; https://pymol.sourceforge.net/ ).
