Intramolecular Electron Transfer versus Substrate Oxidation in Lactoperoxidase: Investigation of Radical Intermediates by Stopped-Flow Absorption Spectrophotometry and (9−285 GHz) Electron Paramagnetic Resonance Spectroscopy

We have combined the information obtained from rapid-scan electronic absorption spectrophotometry and multifrequency (9−295 GHz) electron paramagnetic resonance (EPR) spectroscopy to unequivocally determine the electronic nature of the intermediates in milk lactoperoxidase as a function of pH and to...
