Ferritin is a ubiquitous iron storage and detoxification protein found highly conserved in species from becera to pasto humans. In mammals ferritin is composed of two functionally and genetically distinct subunit types H than-21.000 Da and L light -19.000 Da) subunits which co-assemble in various ratios with tissue specific distribution to form a shell-ike proien. The subuntis responsible for the fast conversion of Fe (II) to Fe (II) by dioxygen (or H202) whereas the L-subunit is thought to contribute to the nucleation of the iron core. In the present work, we investigated the iron oxidation and deposition mechanism in two recombinant heteropolymers ferritin samples of -20H-4L (termed H/L) and -22L2H (termed L'H) ratios. Data indicates that in ontation cours mainly on the H-subunit with a stoichiometry of 2Fe (W):102. suggesting formation of H202 Source aises org
