IntEnz Enzyme Nomenclature


Accepted name:
Cypridina-luciferin 2-monooxygenase
Other names:
Cypridina luciferase
Cypridina-type luciferase
luciferase (Cypridina luciferin)
Systematic name:
Cypridina-luciferin:oxygen 2-oxidoreductase (decarboxylating)



Cypridina is a bioluminescent crustacea. The luciferins (and presumably the luciferases, since they cross-react) of some luminous fish (e.g. Apogon, Parapriacanthus, Porichthys) are apparently similar. The enzyme may be assayed by measurement of light emission.
