Figure 6. Stability of [2Fe-2S] forms of I151A and D154A FNR.

Figure 6

Plots of A420 against time for aerobic samples of [2Fe-2S] forms of (A) wild-type FNR (13 μM); (B) D154A FNR (23 μM); and (C) I151A FNR (13 μM). The data (grey lines) were fitted to a single exponential function (black lines, see the ‘Data analysis’ section) yielding pseudo-first-order rate constants. Inset: absorption spectra of isolated [2Fe-2S] wild-type, D154A FNR and I151A FNR respectively.
