Note 7 — Chapter V · THE CHEMISTRY OF LIGHT PRODUCTION, PART I
Reading edition
is unfortunate that Dubois (1918 b) has used the term oxyluciferine in a quite different sense from the present use. He regards oxyluciferine as a substance still capable of giving light by autoöxidation, and represents the steps in luminescence as follows:
"Co-luciférase+ preluciférine= luciférine.
Luciférase+ luciférine= oxyluciférine.
Oxyluciférine+ oxygéne= lumiérè."
I should represent them as follows:
Luciferin + oxygen ⇆ oxyluciferin.
The reaction proceeds to right with light production only in presence of luciferase.
