Global parameters estimated by theoretical simulation of the background-subtracted experimental current–voltage profiles.

entry	NAcMP	MP-11 (Cyt c)
Γ/pmol cm–2 a	20	23
E°′app/mV (Ag/AgCl)	–200	–230

^aThese values were determined from CVs obtained in 0.1 M phosphate buffer solution without H₂O₂.

^bThe parameter was fixed at 0.5 by assuming a symmetrical energy barrier of the electrode reaction.
