Comparative analysis of electron transfer reactions

Parameters	Diferrous MauG to quinone MADH	PreMADH to bisFe(IV) MauG
ΔG°(kJ mol⁻¹)	−24.9	(−28.9) – (+28.9)^a
H_AB (cm⁻¹)	0.013 ± 0.003	17.9 — 20.2 ± 12.8^a
r (Å, β=1.1 Å⁻¹)	21.3 ± 0.4	8.1 ± 1.2
r (Å, β=1.4 Å⁻¹)	17.4 ± 0.3	7.0 ± 0.9
λ(eV)	1.80 ± 0.04	1.97 — 3.18 ± 0.14^a

As discussed in the text, a range of ΔG°values corresponding toΔE_m values from −300 mV to +300 mV was used when analyzing this reaction. The corresponding range of H_AB and λ values are listed for this reaction. The r values which were obtained did not vary with ΔG° over this range.
