HERFD-XANES spectroscopy. (a) Normalized Mn K-edge HERFD-XANES spectra of wild-type and Gln143Asn MnSOD enzymes both in resting and H2O2-soaked forms. The inset shows a magnified view of the pre-edge region (6537–6543 eV), along with their individual pre-edge intensities. (b, c) Manganese redox state and/or H2O2 treatment affects the individual DFT-derived ESP charges of the manganese primary coordination-sphere residues.
