释义 | luciferinn. Biology.

Royal Microsc. Soc. 26 From the luminous parts of the animal the author [sc. R. Dubois] has succeeded in extracting two substances, the contact of which in the water, determines the appearance of the light. One of them was obtained in the crystalline state... It is soluble in water, and hardly soluble in alcohol; it may be called luciferine. The other body is an active albuminoid of the class of soluble ferments, and may be called luciferase. 1920 Nature 26 Aug. 843/1 The production of light by animals is due to the burning or oxidation of a substance called luciferin in the presence of an enzyme or catalyst called luciferase. 1952 E. N. Harvey Bioluminescence p. xi Luciferin and luciferase are general names used for these compounds manufactured by luminous animals, but it is probable that the luciferin or luciferase from a species in one group may be quite different chemically from that in another. 1954 Harvey & Tsuji in Jrnl. Cell. & Compar. Physiol. XLIV. 71 Luciferin may properly be defined as the oxidizable substance supplying molecules capable of absorbing enough excess energy to emit in the visible region. 1966 Johnson & Haneda Bioluminescence in Progress 10 Bacterial luciferin has become a matter of definition... FMNH2 may be considered the ‘luciferin’ of this system. 1971 Country Life 9 Sept. 605/1 The luciferin, or light-producing material, in a glow-worm's body is oxidised and broken down, with the aid of an enzyme called luciferase, to release light energy with practically no wastage.
