An iron-rich protein, DpsAHsal, was isolated from the archaeon Halobacterium salinarum sharing a sequence identity of 35% with the starvation-induced DNA-binding protein, DpsA, of Synechecoccus sp. PCC7942. It consists of 20-kDa subunits forming a dodecameric structure. The protein exhibits a ferric iron loading of up to 100 Fe ions per mole of holoprotein. CD spectra and secondary structure calculations are consistent with an
