Opening protein pores with chaotropes enhances Fe reduction and chelation of Fe from the ferritin biomineral
Iron is concentrated in ferritin, a spherical protein with a capacious cavity for ferric nanominerals of <4,500 Fe atoms. Global ferritin structure is very stable, resisting 6 M urea and heat (85°C) at neutral pH. Eight pores, each formed by six helices from 3 of the 24 polypeptide subunits, rest...
