Photoinduced Oxidation of Microperoxidase-8:  Generation of Ferryl and Cation-Radical Porphyrins

The electron-transfer reactivity of microperoxidase-8 (MP8), the heme octapeptide derived from enzymatic cleavage of cytochrome c, has been studied by nanosecond flash photolysis methods. Ferric MP8 is rapidly oxidized by photogenerated Ru(bpy)3 3+ in acidic solutions to a ferric cation-radical porp...
