Biological blue‐light photoreceptor proteins with LOV domains form a photoadduct of flavin and cysteine. These proteins also enable the photoreaction of flavin with methylmercaptane and protect the adduct from hydrolysis. The FMN semiquinone radical is proposed as an intermediate in the mechanism of the wild‐type proteins.
