FIGURE 4.
Dynamics of CO after photo-dissociation from the entire sGC and from the isolated heme domain β1(190). A, transient spectra at selected time delays after photo-dissociation of CO from full-length sGC. B, transient spectra at selected time delays after photo-dissociation of CO from β1(190). C, kinetics of CO geminate rebinding to sGC compared with β1(190) calculated by global analysis, representing the evolution of the entire difference spectrum. A 4-ps component was included in the fitting function to take into account the initial excited states decay.
