In the catalytic cycle of Cytochrome P450, the generation of [(porphyrin)+•FeIV(O)] from [(porphyrin)FeIII(OOH)] involves
1
One electron oxidation of [(porphyrin)FeIII(OOH)]
2
Formation of the intermediate [(porphyrin)FeIV(OH)]
3
Homolytic O-O cleavage of [(porphyrin)FeIV(OOH)]
4
Heterolytic O-O cleavage of [(porphyrin)FeIII(OOH)]
