Two different diiron centres have been characterized by Mossbauer and EPR spectroscopies in the oxygenase part of phenol hydroxylase from Pseudomonas. In one centre the irons were suggested to be oxo-bridged whereas for the other a hydroxo bridge was preferred.170... 

Formation of metal-oxo species first became realistic in model studies on heme oxygenases (shunt path), and it has also become popular in nonheme systems. As for the metal-jd-peroxo species, the distinctive example of model study has appeared in the copper enzymes. The type 7 peroxo species has been proposed first based on models for dicopper oxy-hemocyanin [19, 20] before demonstration of the same oxygen bonding in enzyme [13]. The type 7 x-peroxo structure has been applied to diiron species in sMMO [14] in addition to 6 [21]. (see Chapter 8)...
