Human h chain ferritin
WebFerritin, the iron storage protein, has drawn the attention of the scientific community in recent decades. Its unique structure consists of a spherical shell composed of 24 peptide subunits [ 1 ]. In mammals, two types of subunits are present: a heavy (21 kDa) and a light (19 kDa) chain [ 2 ]. WebFerritin stores iron as ferrihydrite inside a shell composed of H and L protein chains. H chains contain ferroxidase centres catalysing Fe2+ oxidation, while L chains lack these centres but seem to promote ferrihydrite nucleation. Mossbauer spectroscopic studies of recombinant H-chain ferritins show the following: (1) fast Fe2+ oxidation is associated …
