In enzymology, an Oplophorus-luciferin 2-monooxygenase (EC 1.13.12.13) is a luciferase, an enzyme, from the deep-sea shrimp Oplophorus gracilirostris that catalyzes the chemical reaction:

coelenterazine + O₂ $\rightarrow$ coelenteramide + CO₂ + hν

Thus, the two substrates of this enzyme are the luciferin, Coelenterazine and O₂, whereas its 3 products are the oxyluciferin, Coelenteramide, CO₂, and light. 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 Oplophorus-luciferin:oxygen 2-oxidoreductase (decarboxylating). This enzyme is also called Oplophorus luciferase.
