In enzymology, an Oplophorus-luciferin 2-monooxygenase (EC 1.13.12.13) is an enzyme that catalyzes the chemical reaction

Oplophorus luciferin + O2 \rightleftharpoons oxidized Oplophorus luciferin + CO2 + hnu

Thus, the two substrates of this enzyme are Oplophorus luciferin and O2, whereas its 3 products are oxidized Oplophorus luciferin, CO2, and hn.

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.
