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. WebThe FMN chromophore provides the LOV domain with a weak intrinsic green fluorescence when excited with UV-A/ blue light (14, 15). Mutagenesis of the active-site cysteine resi-due abolishes LOV domain photochemistry and increases its fluorescence (11, 16), making photochemically inactivated
