additional information

Escherichia coli

although H2O2 is a product of dioxygen reduction in FtnA and oxidation occurs with a stoichiometry of Fe2+/O2 about 3:1 most of the H2O2 produced is consumed in subsequent reactions with a 2:1 Fe2+/H2O2 stoichiometry, thus suppressing hydroxyl-radical formation
