Types of luciferin Note that luciferins should not be confused with the enzyme luciferase. Luciferins are a substrate for luciferase. Luciferins are oxidized in the presence of the enzyme luciferase to produce oxyluciferin and energy in the form of light. There are five general types of luciferins. Firefly luciferin Firefly luciferin is the luciferin found in fireflies. It is the substrate of luciferase (EC 1.13.12.7) Bacterial luciferin Bacterial luciferin is a type of luciferin found in bacteria, some squids and fishes. It consists of a long-chain aldehyde and a reduced riboflavin phosphate. Dinoflagellate luciferin Dinoflagellate luciferin is a chlorophyll derivative and is found in dinoflagellates, which are often responsible for the phenomenon of nighttime ocean phosphorescence. A very similar type of luciferin is found in some types of euphausiid shrimp. Vargulin
