Role of Dps (DNA-binding proteins from starved cells) aggregation on DNA.
Chiancone E, Ceci P. Chiancone E, et al. Front Biosci (Landmark Ed). 2010 Jan 1;15:122-31. doi: 10.2741/3610. Front Biosci (Landmark Ed). 2010. PMID: 20036810 Review.
Thermosynechococcus elongatus DpsA binds Zn(II) at a unique three histidine-containing ferroxidase center and utilizes O2 as iron oxidant with very high efficiency, unlike the typical Dps proteins.

Synthesis of iron oxide nanoparticles in Listeria innocua Dps (DNA-binding protein from starved cells): a study with the wild-type protein and a catalytic centre mutant.
