EC 1.13.12.6

Accepted name: Cypridina-luciferin 2-monooxygenase

Reaction: Cypridina luciferin + O2 = oxidized Cypridina luciferin + CO2 +

Glossary: Cypridina-luciferin = (3-{3,7-dihydro-6-(1H-indol-3-yl)-2-[(S)-1-methylpropyl]-3-oxoimidazo[1,2-a]pyrazin-8-yl}propyl)guanidine

Other name(s): Cypridina-type luciferase; luciferase (Cypridina luciferin); Cypridina luciferase

Systematic name: Cypridina-luciferin:oxygen 2-oxidoreductase (decarboxylating)

Comments: 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.
