Protonation of the oxygen axial ligand in galactose oxidase model compounds as seen with high resolution X-ray emission experiments and FEFF simulations.
X-ray Emission Spectroscopy (XES) crossover peaks were shown to be sensitive to the protonation state of solvent mols. in the Zn protein carbonic anhydrase and its model compds. Here we extend such studies to galactose oxidase models i.e. Cu(ii) open d-shell systems, illustrating that XES combined with FEFF8 simulations reflect changes in the protonation state of the phenolate ligand for the copper center.
