New luciferases and photoproteins in marine annelids (Annelida) and bioluminescent systems dependent on coelenterazine


Bioluminescence, the emission of cold and visible light by living organisms, is a phenomenon produced from the oxidation of a substrate (generically called luciferin) catalyzed by enzymes resulting in photons of visible light. All these reactions use a variety of photoproteins and luciferases, which are currently employed as versatile tools in basic research and for applied purposes.Therefore, this project aims to understand the process of light emission in marine bioluminescent organisms insufficiently researched, such as, in the annelids Chaetopterus variopedatus and Harmothoe sp. Furthermore, organisms that use the molecule of coelenterazine as a substrate, such as cnidarians and ctenophores, collected recently by our group in expeditions along the coast of Brazil and abroad are also targets of the study. Thus, through isolation, cloning, expression and characterization of photoproteins/luciferases present in these organisms, as well as in the purification of new luminescent substrates, the intention is to broaden the understanding of chemical/biochemical mechanisms and ecological functions of bioluminescence.
