LC-MS/MS Proteoform Profiling Exposes Cytochrome c Peroxidase Self-Oxidation in Mitochondria and Functionally Important Hole Hopping from Its Heme

Author(s): Kathiresan M; English AM;

LC-MS/MS profiling reveals that the proteoforms of cytochrome c peroxidase (Ccp1) isolated from respiring yeast mitochondria are oxidized at numerous Met, Trp, and Tyr residues. In vitro oxidation of recombinant Ccp1 by H2O2 in the absence of its reducing substrate, ferrocytochrome c, gives rise to similar proteoforms, indicating uncoupling of Ccp1 oxidat ...
