Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (DSBE_ECOLI | P0AA86)
molecular function
    GO:0015036    disulfide oxidoreductase activity    Catalysis of the reaction: substrate with reduced sulfide groups = substrate with oxidized disulfide bonds.
    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:0045454    cell redox homeostasis    Any process that maintains the redox environment of a cell or compartment within a cell.
    GO:0017004    cytochrome complex assembly    The aggregation, arrangement and bonding together of a cytochrome complex. A cytochrome complex is a protein complex in which at least one of the proteins is a cytochrome, i.e. a heme-containing protein involved in catalysis of redox reactions.
    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:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0031237    intrinsic component of periplasmic side of plasma membrane    The component of a plasma membrane consisting of gene products and protein complexes that penetrate the periplasmic side of the plasma membrane only, either directly or via some covalently attached hydrophobic anchor.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0030288    outer membrane-bounded periplasmic space    The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
    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.
