A role for Dps ferritin activity in long-term survival of Escherichia coli.

Microbiology spectrum - 7 Oct 2025

Serebnitskiy Zlatas, Orban Katie, Finkel Steven E

Abstract excerpt

Escherichia coli expresses three ferritins that store acquired iron by oxidizing soluble Fe(II) to insoluble Fe(III), which can accumulate and later be utilized in cellular processes. Although bacterioferritin (Bfr) and ferritin (FtnA) sequester more Fe(III) atoms per multimeric complex, the abundance of the DNA-binding protein from starved cells (Dps), coupled with its preference for hydrogen peroxide as an...
