Abstract:

The ability of succinate-cytochrome c reductase (SCR) reduced cytochrome c to scavenge H2O2 was investigated. H2O2, whether added or produced by SCR, was efficiently removed when cytochrome c was reduced by SCR. On the other hand, ferrocytochrome c underwent re-oxidization when H2O2 was added. Thus, these results indicate that cytochrome c reduced by succinate-cytochrome c reductase has the ability to regulate H2O2 in mitochondria.
