E. Newton Harvey,
The Nature of Animal Light
“ Of the names, luciferin, luciferase, preluciferin or proluciferin, co-luciferase, photogenin, photophelein, oxyluciferin, luciferesceine, I believe that only proluciferin, luciferin, oxyluciferin, luciferase and photophelein stand for substances which are really significant for the theory of light production. Luciferin is the heat resistant, dialyzable substance which takes up oxygen and oxidizes with light production in the presence of the heat sensitive, non-dialyzing, enzyme-like luciferase. ”
