(a) Fobs(2.5 ms) − Fobs(dark) maps contoured at ±3σ around the FMN chromophore and surrounding residues. Pairs of positive (blue mesh) and negative peaks (gold mesh) of density are indicated with an arrow. (b) Close-up superposition of the model coordinates of the refined light activated state (purple) and the dark state (gray) from SSX data on the flavin region, showing the rotation of Gln120 that is hydrogen bonded to the protonated N5 of FMN. (c) Close-up view on the loop connecting β-strand H and I.
