SOLVED: The enzyme called luciferase catalyzes the reaction that allows fireflies to emit light The first step in this reaction involves the substrate compound called luciferin , reacting with ATP. The luciferase enzyme has been crystallized bound to the product of this one-step reaction, as shown in the Pymol diagram below.
