molecular function
    GO:0052873    FMN reductase (NADPH) activity    Catalysis of the reaction: FMNH2 + NADP+ = FMN + NADPH + 2 H+.
    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.
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.
