Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (THIO_MYCTU | P9WG67)
molecular function
    GO:0080007    S-nitrosoglutathione reductase activity    Catalysis of the reaction: glutathione N-hydroxysulfenamide + NADH + H+ = S-nitrosoglutathione + NAD+.
    GO:0015036    disulfide oxidoreductase activity    Catalysis of the reaction: substrate with reduced sulfide groups = substrate with oxidized disulfide bonds.
    GO:0009055    electron carrier activity    Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient.
    GO:0015038    glutathione disulfide oxidoreductase activity    Catalysis of the reaction: 2 glutathione + electron acceptor = glutathione disulfide + electron donor.
    GO:0016671    oxidoreductase activity, acting on a sulfur group of donors, disulfide as acceptor    Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces disulfide.
    GO:0015035    protein disulfide oxidoreductase activity    Catalysis of the reaction: a protein with reduced sulfide groups = a protein with oxidized disulfide bonds.
biological process
    GO:0045454    cell redox homeostasis    Any process that maintains the redox environment of a cell or compartment within a cell.
    GO:0034599    cellular response to oxidative stress    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.
    GO:0006535    cysteine biosynthetic process from serine    The chemical reactions and pathways resulting in the formation of cysteine from other compounds, including serine.
    GO:0052060    evasion or tolerance by symbiont of host-produced nitric oxide    The process in which an organism avoids the effects of nitric oxide produced as a defense response by the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.
    GO:0006662    glycerol ether metabolic process    The chemical reactions and pathways involving glycerol ethers, any anhydride formed between two organic hydroxy compounds, one of which is glycerol.
    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.
    GO:0006457    protein folding    The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.
    GO:0000103    sulfate assimilation    The pathways by which inorganic sulfate is processed and incorporated into sulfated compounds.
cellular component
    GO:0005618    cell wall    The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

Chain A   (THIO_MYCTO | P9WG66)
molecular function
    GO:0015035    protein disulfide oxidoreductase activity    Catalysis of the reaction: a protein with reduced sulfide groups = a protein with oxidized disulfide bonds.

    GO:0045454    cell redox homeostasis    Any process that maintains the redox environment of a cell or compartment within a cell.
    GO:0006662    glycerol ether metabolic process    The chemical reactions and pathways involving glycerol ethers, any anhydride formed between two organic hydroxy compounds, one of which is glycerol.
    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:0005623    cell    The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.
