Figure 3. Oxidation by O2.

Figure 3

Oxidation of GLB-26, induced by photodissociation of CO in the presence of oxygen (650 µM CO and 500 µM oxygen). A. After each laser pulse the fraction of heme which does not rebind first with CO undergoes a fast iron oxidation. B. The spectra recorded 0.5 s subsequent to the CO dissociation are typical of a transition from the steady-state CO to the oxidized spectra.
