a ferric-superoxide species as a primary oxidant to initiate DKP-assembly. Single turnover kinetic isotopeeffects and a substrate analog suggest the probable nature and site for abstraction. The directobservation of CYP-superoxide reactivity rationalizes the atypical outcome of AspB and reveals a new reaction manifold in hemeenzymes.
