Cypridina-luciferin 2-monooxygenase (EC 1.13.12.6) is an enzyme that catalyzes the chemical reaction

 
O2
CO2
 
 
 
oxidized vargulin
+ hν
 

Thus, the two substrates of this enzyme are vargulin and oxygen. Its products are oxidized vargulin, carbon dioxide, and a photon.[1][2][3]

This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O with incorporation of one atom of oxygen (internal monooxygenases o internal mixed-function oxidases). The systematic name of this enzyme class is Cypridina-luciferin:oxygen 2-oxidoreductase (decarboxylating). Other names in common use include Cypridina-type luciferase, luciferase (Cypridina luciferin), and Cypridina luciferase.[4]

The primary sequence was determined by cloning the cDNA.[5]
