Irridiation of RsLOV crystals. (A) Light state structure of RsLOV with electron density corresponding to the light-induced cysteinyl-C4a adduct of Cys55 and FMN (Fo-Fc simulated annealing omit map, obtained by omitting the flavin molecule and Cys55 residue, contoured at 2.2σ in cyan, 0.7σ in gray). The two conformations of Cys55B and flavin are shown in yellow (covalently bound) and green (unbound). (B) FMN binding pocket residues affected by changes in light state conversion. (C) RsLOV structure in the light state with Fo–Fo difference map of light-dark amplitudes (green is +3.5σ, red is −3.5σ).
