ID 1.14.99.21 DE Latia-luciferin monooxygenase (demethylating). CA Latia luciferin + AH2 + 2 O2 = oxidized Latia luciferin + hnu + formate + CA A + CO2 + H2O + H(+). CC -!- Latia luciferin is (E)-2-methyl-4-(2,6,6-trimethyl-1-cyclohex-1-yl)- CC 1-buten-1-ol formate. CC -!- The reaction possibly involves two enzymes, an oxygenase followed by CC a monooxygenase for the actual light-emitting step. //
