Iron is an essential micronutrient for bacteria, functioning as a cofactor in vital processes such electron transport, heme synthesis, and DNA replication. However, excess iron triggers the Fenton reaction, producing harmful reactive oxygen species. To manage this, E. coli has evolved regulatory systems to maintain balance despite its scarcity environment, with free concentrations low 10^-18 M. The iron-binding repressor protein Fur regulates genes involved uptake, transfer, storage. FeoABC system primary route Fe2+ entry, FeoB enabling reduction of Fe3+ transferring it FeoA, which likely prevents wasteful binding negatively charged cellular membranes. This efficient management acquisition storage not only ensures survival but also provides insights into bacterial metabolic strategies optimizing use while minimizing damage from Highlights: crucial functions like replication synthesis. Excess creating uptake balances bacteria. Keywords: homeostasis, system, coli, protein, species
