摘要
The diiron(III) center of the protein R2, a subunit of the ribonucleotide reductase, can be efficiently reduced with diimide to the mixed valence Fe(II)/Fe(III) state, which can be detected EPR spectroscopically. A comparison with the spectra of the mixed valence state of hemerythrin suggests that both Fe atoms are only weakly antiferromagnetically coupled, and are bound via a hydroxo bridge.
