WebOct 16, 2024 · In the C-terminal light-oxygen-voltage (LOV) domain of plant phototropins (LOV2), blue light activation leads to formation of an adduct between a conserved Cys residue and the embedded FMN chromophore, rotation of a conserved Gln (Q513), and unfolding of a helix (Jα-helix) which is coupled to the output domain. WebSep 28, 2024 · Examples of such chromophores include flavin mononucleotide (FMN), the heme catabolic intermediate biliverdin, a protonated retinylidene Schiff base, 4-hydroxybenzylidene rhodanine analogs (HBR), and the Janelia Fluor 635 HaloTag ligand ( Fig. 1H) ( Broch and Gautier, 2024 ).

WebChromophore. Common to all LOV proteins is the blue-light sensitive flavin chromophore, ... (FMN) chromophore in its dark-state form, and a C-terminal Ser-Thr kinase. Upon blue-light absorption, a covalent bond between the FMN chromophore and an adjacent reactive cysteine residue of the apo-protein is formed in the LOV2 domain. WebBoth LOV1 and LOV2 undergo a self-contained photocycle, which involves the formation of a covalent adduct between the FMN chromophore and a conserved active-site cysteine residue (Cys39). Replacement of Cys39 with alanine abolishes the light-induced photochemical reaction of LOV1 and LOV2.
