Figure 1: Starting structures of the AsLOV2-Jα photosensor.
From: Mechanism of signal transduction of the LOV2-Jα photosensor from Avena sativa
(a) Dark-state solution structure of the AsLOV2-Jα system, refined through NMR measurements. (b) AsLOV2 protein core with the adjacent Jα helix and relevant amino acids (violet: Gln1029; red: Asp1056, Gln1013; green: Glu1034, Gln995). (c) Difference in the starting structures between dark- and adduct-state forms, structurally only differing with regard to the covalent bond of the CFN, and relevant amino acids surrounding the FMN chromophore (cyan: C-atom; red: O-atom; blue: N-atom; white: H-atom; brown: P-atom; yellow: S-atom).
