Figure 7

(2mF obs − DF calc, αcalc) electron-density map in data sets for the dark and light states of AtPhot2LOV2 at 100 K. (a) Structure of the dark state at the position of the chromophore FMN (maps contoured at a 1.5σ level). (b) Structure of the light state recorded with an accumulated dose of 24 kGy (maps contoured at a 1.5σ level). (c) [F obs(2) − F obs(1), αcalc(1)] Fourier difference map calculated between the second and the first data sets of the irradiation series on the AtPhot2LOV2 light state, highlighting the very fast specific radiation damage to the Cys426–FMN covalent bond (map contoured at a ±4.0σ level). (d) Structure of the light state recorded with a total accumulated dose of 48 kGy (maps contoured at a 1.5σ level).
