Figure 7
Processing of kinetic data for the X-ray reduction of cytochrome c′ from S. frigidimarina. The panels in the second row show the smoothed data, those in the third row show the peaks identified in the first and the last spectrum and those in the fourth row show kinetic slices through those peaks. The spectrum of the ferric protein (blue) is rapidly interconverted to that of the ferrous form. Bottom panel: the dose-dependence of absorbance at three spectral peaks. Changes are largely complete after an absorbed dose of 1 MGy. |
