The lantern shark genus Etmopterus contains approximately 40 species of deep-sea bioluminescent cartilaginous fishes. They emit blue light mainly from the ventral body surface. The biological functions of this bioluminescence have been discussed based on the luminescence patterns, but the bioluminescence mechanism remains uncertain. In this study, we detected both coelenterazine and coelenterazine-dependent luciferase activity in the ventral photophore tissue of Etmopterus molleri. The results suggested that bioluminescence in lantern sharks is produced using coelenterazine as the substrate for the luciferin-luciferase reaction, as some luminous bony fishes.

Etmopterus 灯笼鲨使用腔肠素作为其荧光素-荧光素酶生物发光系统的底物

灯笼鲨属Etmopterus包含大约 40 种深海生物发光软骨鱼。它们主要从腹侧体表发出蓝光。已经基于发光模式讨论了这种生物发光的生物学功能,但生物发光机制仍然不确定。在这项研究中,我们在Etmopterus molleri腹侧发光组织中检测到腔肠素和腔肠素依赖性荧光素酶活性。结果表明,灯笼鲨的生物发光是使用腔肠素作为荧光素-荧光素酶反应的底物产生的,就像一些发光的硬骨鱼一样。
