DNA-binding proteins from starved cells (Dps) are homododecameric nanocages, with N- and C-terminal tail extensions of variable length and amino acid composition. They accumulate iron in the form of a ferrihydrite mineral core and are capable of bind

Iron–sulfur centers are widespread in living organisms, mostly performing electron transfer functions, either in electron transfer chains or as part of multi-enzymatic complexes, while being also present in enzyme active sites, handling substrate c

DNA-binding proteins from starved cells (Dps) are members of the ferritin family of proteins found in prokaryotes, with hollow rounded cube-like structures, composed of 12 equal subunits. These protein nanocages are bifunctional enzymes that protect
