Reference Woodmansee AN, Imlay JA. Reduced flavins promote oxidative DNA damage in non-respiring Escherichia coli by delivering electrons to intracellular free iron. J Biol Chem. 2002 Sep 13 277(37):34055-66 p.34059 right columnPubMed ID12080063
Method Intracellular free iron was quantified by electron paramagnetic resonance (EPR) spectroscopy (Keyer et al., 1996, PMID 8942986). For growth conditions see p. 34057 left column
Comments The majority of iron ions is probably bound. Note- total iron conc. of 18 mM (7,000,000 Fe ions) given by link
