Chain A   (Q88NF7_PSEPK | Q88NF7)
molecular function
    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:0003959    NADPH dehydrogenase activity    Catalysis of the reaction: NADPH + H+ + acceptor = NADP+ + reduced acceptor.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    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:0018548    pentaerythritol trinitrate reductase activity    Catalysis of the reaction: pentaerythritol trinitrate + NADPH = NADP+ + nitrate + pentaerythritol dinitrate.
    GO:0052690    trichloro-p-hydroquinone reductive dehalogenase activity    Catalysis of the reaction: 2,3,6-trichlorohydroquinone + 2 glutathione = 2,6-dichlorohydroquinone + glutathione disulfide + HCl.
biological process
    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.
