Abstract
Many living organisms emit light, a phenomenon known as bioluminescence. The energy required for light production is generated by the oxidation of a small organic molecule, luciferin, catalyzed by a specific enzyme, luciferase. Luminous taxa have currently been reported from about 800 genera. The chemical nature and mechanisms of action of the few known types of bioluminescence substrates (luciferins) are as diverse as their phylogenetic distribution. Despite being widely used in reporter technologies, bioluminescent systems are largely understudied. Of at least forty different bioluminescent systems thought to exist in nature, molecular components of only ten light-emitting reactions are known, and the full biochemical pathway leading to light emission is only understood for two of them. In this talk, the current status and perspectives, in the context of postgenomic era, of novel bioluminescence systems including fungi, earthworms, and marine polychaetes will be reviewed.
