The amplitudes of the exponential 3FMN absorption decays, Absi0 (A) and the amplitudes Ai of the different 3FMN group contributions to the 1O2 phosphorescence signal (see Eq. 1) (B) in intact protein (red circles), in oxidized protein (green triangles), and in water (black squares) as a function of the irradiation time of AsLOV2 C450A. The solid lines represent the results of the fitting procedures.
