(A) Steady-state spectra of PaBphP Pr state. Arrows mark the excitation wavelength and gated fluorescence wavelengths. (B) Measured TRES of WT PaBphP at selected delay times normalized at 746 nm. (C, D) Normalized femtosecond-resolved fluorescence transients of WT PaBphP gated at typical wavelengths with 600-nm excitation. (E, F) Normalized femtosecond-resolved fluorescence transients of WT PaBphP and mutants gated at 700 nm and 840 nm with 600-nm excitation wavelength. The gray dashed lines are the baseline at zero. Note that the delay time is shown on linear scale before 20 ps and logarithmic scale thereafter.
