Table 3. Tabulated Rate Constants for Haem to T1Cu Electron Transfer in Native RpNiR, the Natural 2-Component AxNiR-Axcytc₅₅₁, and the Reverse Engineered Constituent RpNiR Proteins^a.

CuNiR construct	k (mM^–1 s^–1)	k_obs (s^–1)
WT RpNiR	n/a	16.8 ± 0.2
WT AxNiR and WT Axcyt c₅₅₁	2.6 ± 0.1	0.26–26^b
RpNiR-core and RpNiR cyt c	0.9 ± 0.1	0.09–9^b

Data are shown ± error of fit.

k_obs was calculated for the 2-component systems by multiplying the second-order rate constants (k) by the average protein concentrations found within Gram-negative bacteria (0.1–10 μM).
