Chemical nature of bioluminescence systems in coelenterates.
Analysis of substances involved in light-emitting reactions among bioluminescent coelenterates has revealed a pronounced uniformity in the structural features of initial reactants, i.e., "luciferins" and photo-protein chromophores, as well as the light-emitter product. This product is structurally identical among the different classes of coelenterates: Hydrozoa (the jellyfish, Aequorea), Anthoz...
متن کاملLumisomes, the cellular site of bioluminescence in coelenterates.
From ten species of bioluminescent coelenterates we have isolated a membrane-enclosed subcellular particle that is apparently responsible for the bioluminescence in these animals. The animals investigated were species of Obelia and Clyfia (from the class Hydrozoa) and species of Renilta, Pfilosarcus, Sfylafula, Acanfhopfilum, and Parazoanfhus (from the class Anthozoa). By electron microscopy th...
متن کاملCan coelenterates make coelenterazine? Dietary requirement for luciferin in cnidarian bioluminescence.
In the calcium-activated photoprotein aequorin, light is produced by the oxidation of coelenterazine, the luciferin used by at least seven marine phyla. However, despite extensive research on photoproteins, there has been no evidence to indicate the origin of coelenterazine within the phylum Cnidaria. Here we report that the hydromedusa Aequorea victoria is unable to produce its own coelenteraz...
متن کاملThe Nature and Control of Reactions in Bioluminescence
On the basis of available data with regard to the chemical and physical properties of the "substrate" luciferin (LH(2)) and enzyme, luciferase (A), and of kinetic data derived both from the reaction in extracts of Cypridina, and from the luminescence of intact bacteria, the fundamental reactions involved in the phenomenon of bioluminescence have been schematized. These reactions provide a satis...
