Electrochemical parameters for the haemprotein–HXT–Au electrode in 0.1 M phosphate buffer solution (pH 7.0) at 25°C.

entry	NAcMP	MP-11 (Cyt c)
Γ/pmol cm–2 a	20	23
E°′/mV (Ag/AgCl)	–335	–327
ΔEp/mV	69	123
kDET/s–1 b	1.7	0.71

^aThe value was determined by integration of the charge under the cathodic peak of CV.

^bThe rate constant was calculated by the literature method [34].
