“…In the case of the firefly, the bioluminescence matches the fluorescence of the oxyluciferin, the oxidized product of the consumable substrate . Similarly, in bacterial systems, the bioluminescence spectra also matches the fluorescence of a flavin cation, which is oxidized in the reaction and later regenerated .…”

Characterization of an anthraquinone fluor from the bioluminescent, pelagic polychaete Tomopteris

Tomopteris is a cosmopolitan genus of polychaetes. Many species produce yellow luminescence in the parapodia when stimulated. Yellow bioluminescence is rare in the ocean and the components of this luminescent reaction have not been identified. Only a brief description half a century ago noted a fluorescence in the parapodia with a remarkably similar spectrum to the bioluminescence, which suggested that it may be the luciferin or terminal light-emitter. Here we report the isolation of the fluorescent yellow-orange pigment found in the luminous exudate and in the body of the animals. LCMS revealed the mass to be 270m/z with a molecular formula of C15H10O5, which ultimately was shown to be aloe-emodin, an anthraquinone previously found in plants. We speculate that aloe-emodin could be a factor for resonant-energy transfer or the oxyluciferin for Tomopteris bioluminescence.
