Effect of the silver nitrate addition on the oxidation state of the hemes in Gs as demonstrated by the baseline-corrected absorption of the Q band as function of time (used in Figure 5B). A) Spectra showing the initial decrease of the Fe2+ absorption between 0.5 and 1 minute.Only these two lines are shown at low absorption.
