Extended Data Fig. 6: Complete set of EPR spectra recorded over the course of the FEcv-EPR experiment under catalytic conditions.

EPR spectra obtained during the FECV-EPR measurements during both forward and reverse CV scans in the presence of 20 mM MBA under catalytic conditions. Similarly, to the non-turnover spectra, each EPR spectrum covers ~21 mV. During the forward CV scan, the intensity of the EPR spectra decreases with increasing the potential, reaching a minimum at 1000 mV. During the reverse CV scan, the intensity increases back to reach a maximum at 700 mV.
