molecular function
    GO:0047646    alkanal monooxygenase (FMN-linked) activity    Catalysis of the reaction: R-CHO + reduced FMN + O2 = R-COOH + FMN + H2O + light.
    GO:0004497    monooxygenase activity    Catalysis of the incorporation of one atom from molecular oxygen into a compound and the reduction of the other atom of oxygen to water.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0016705    oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen    Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from each of two donors, and molecular oxygen is reduced or incorporated into a donor.
biological process
    GO:0008218    bioluminescence    The production of light by certain enzyme-catalyzed reactions in cells.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
