Encapsulation of cytochrome C in A. fulgidus-human chimeric ferritin. Ferritin dimers were previously S-carboxymethylated with iodoacetic acid to enhance the net negative charge of the inner cavity. Reassembly of the protein cage was then achieved at neutral pH in the presence of cytochrome C and divalent cations.
