Comparisons of dinuclear iron centers in ferritins and other proteins

3 Comparisons of dinuclear iron centers in ferritins and otHer proteins 

Although they show little overall sequence identity, the dinuclear centers of the three prototype ferritins, particularly that of EcBfr, are remarkably similar in both amino acid residues and their geometry to those of the class 2 diiron proteins that comprises the ribonucleotide reductase R2 subunit (RNR R2), the methane monooxygenase hydroxylase component (MMOH), rubrerythrin (Rr) and several other
