Asymmetric Unit(hide GO term definitions)
Chain A,B,C,D   (Q389T8_TRYB2 | Q389T8)
molecular function
    GO:0015036    disulfide oxidoreductase activity    Catalysis of the reaction: substrate with reduced sulfide groups = substrate with oxidized disulfide bonds.
    GO:0050660    flavin adenine dinucleotide binding    Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
    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:0016668    oxidoreductase activity, acting on a sulfur group of donors, NAD(P) as acceptor    Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces NAD or NADP.
    GO:0015042    trypanothione-disulfide reductase activity    Catalysis of the reaction: NADP+ + trypanothione = NADPH + H+ + trypanothione disulfide.
biological process
    GO:0045454    cell redox homeostasis    Any process that maintains the redox environment of a cell or compartment within a cell.
    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
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
