Bacterial iron homeostasis is often regulated by regulators of the Fur family, including in Bacillus subtilis both Fur (left; modeled on PDB 3MWM) and PerR. Resistance to iron (yellow) overload is conferred primarily by induction of a newly assigned iron efflux P1B‐4‐type ATPase, PfeT (top, represented by a P1B‐type ATPase from L. pneumophila PDB 4BBJ) with a secondary contribution from the Fe sequestration protein MrgA (right; represented by E. coli Dps; PDB 1DPS). For details, see the article by Guan et al. on pp. 787–803 of this issue.

Magnetospirillum gryphiswaldense MSR‐1 synthesizes membrane‐enclosed magnetite (Fe3O4) nanoparticles, magnetosomes, for magnetotaxis. Formation of these organelles requires MamB, a cation diffusion facilitator (CDF) protein with two roles: it initiates magnetosome vesicle formation in a transport independent process and transports iron for magnetite nucleation. For details, see the article by Uebe et al. on pp. 542–557 of this issue.

Molecular modeling of the Trypanosoma brucei aminopurine transporter P2/TbAT1, implicated in resistance to both diamidine and melaminophenyl arsenical classes of drugs, predicts that residues F19 (left), D140 (top) and F316 (right) interact with substrates. The binding site of adenosine (green carbon atoms) and diminazene (yellow carbon atoms) is shown with hydrogen bonds between Asp140 and bound adenosine in dashed blue lines. For details, see the article by Munday et al. on pp. 887–900 of this issue.

In the cyanobacterium Synechocystis sp PCC6803 the repair protease FtsH2 is located in the thylakoid membranes, but has a different distribution from the photosynthetic reaction centers suggesting the existence of dedicated repair zones. False‐color 3D surface plots from fluorescence micrographs show the distribution of fluorescence from chlorophyll (left) and GFP‐tagged FtsH2 (right) in cells grown under low light (top) or high light (bottom). For details, see the article by Sacharz et al. on pp. 448–462 of this issue.
