ENTRY       EC 1.13.12.6
NAME        Cypridina-luciferin 2-monooxygenase
            Cypridina-type luciferase
CLASS       Oxidoreductases
            Acting on paired donors with incorporation of molecular oxygen
            (oxygenases)
            With incorporation of one atom of oxygen (internal monooxygenases
            or internal mixed function oxidases)
SYSNAME     Cypridina-luciferin:oxygen 2-oxidoreductase(decarboxylating)
REACTION    Cypridina luciferin + O2 = Oxidized Cypridina luciferin +
            CO2 + hv
SUBSTRATE   Cypridina luciferin
            O2
PRODUCT     Oxidized Cypridina luciferin
            CO2
            hv
COMMENT     Luciferin from the bioluminescent crustacean Cypridina is
            [3-[3,7-dihydro-6-(1H-indol-3-yl)]-2-[(S)-1-methyl-6-propyl]-
            -3-oxoimidazo[1,2a]pyrazin-8-yl]propyl]guanidine. 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 emmission.
