(A) Parallel-mode CW EPR spectrum of CaMn3+SODc and ScMn3+SOD oxidized by potassium permanganate ([ScMnSOD]:KMnO4 = 1:0.75) and of ScMn3+SOD treated with 1 equivalent of sodium ascorbate. (B) The deconvolution of the two spectra (top two spectra in panel A) of the permanganate-oxidized species shows two components, one assigned to a Mn3+ center with a 5A1g ground state and one with a 5B1g ground state. Instrument settings: ν = 9.3959 GHz; microwave power = 32 mW; sweep rate = 1.81 mT/s; temp = 4.9 K.
