CD spectra. (A) Near-UV CD spectra of the BLG/PPIX complex at pH 9. In comparison with the initial (black) and nonirradiated (blue) spectra, the irradiated complex (red) shows a near suppression of the Trp peak at 286 nm. (B) Far-UV CD spectra at pH 6. The spectra of BLG (black) superimposes with the spectrum of the BLG/PPIX complex before irradiation (blue), the spectrum of the nonirradiated complex (red), and the spectrum of the irradiated complex (green). (C) Far-UV CD spectra at pH 9. The spectra of BLG (black) superimposes with the spectrum of the BLG/PPIX complex before irradiation (orange), the spectrum of the nonirradiated complex (yellow), and BLG (green) after a time equivalent to the irradiation time. The spectrum of the irradiated complex in air (red) and deoxygenated (blue) are shifted to smaller wavelengths and show a slightly deeper trough.
