Extended Data Fig. 4 |. Spectroelectrochemical determination of redox potentials of selected myoglobin mutants.
The proteins were analyzed in 20 mM TRIS-HCl (pH 8.0) at 20 °C in presence of the mediator (100 μM phenazine sulfate). The redox potentials (vs Ag/AgCl) are summarized in Supplementary Table 5.
