molecular function
    GO:0004155    6,7-dihydropteridine reductase activity    Catalysis of the reaction: NADP+ + 5,6,7,8-tetrahydropteridine = NADPH + H+ + 6,7-dihydropteridine.
    GO:0010181    FMN binding    Interacting selectively and non-covalently with flavin mono nucleotide. Flavin mono nucleotide (FMN) is the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes.
    GO:0018545    NAD(P)H nitroreductase activity    Catalysis of the conversion of a nitrate group to an amino or hydroxylamino group on toluene or a toluene derivative.
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    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:0046256    2,4,6-trinitrotoluene catabolic process    The chemical reactions and pathways resulting in the breakdown of 2,4,6-trinitrotoluene, 1-methyl-2,4,6-trinitrobenzene, a highly explosive pale yellow crystalline solid.
    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.
cellular component
