Recombinant H-chain ferritins: effects of changes in the 3-fold channels.
Human H-chain ferritins bearing sequence changes in the 3-fold channels have been expressed in E. coli to investigate the role of these channels in iron-storage processes. The proteins assemble into shells resembling those of native ferritins. Iron uptake measurements indicate that residues in the 3-fold channels are involved neither in initial Fe(II)-oxidation nor in iron-core nucleation.
