Chain A   (FHUA_ECOLI | P06971)
molecular function
    GO:0048037    cofactor binding    Interacting selectively and non-covalently with a cofactor, a substance that is required for the activity of an enzyme or other protein. Cofactors may be inorganic, such as the metal atoms zinc, iron, and copper in certain forms, or organic, in which case they are referred to as coenzymes. Cofactors may either be bound tightly to active sites or bind loosely with the substrate.
    GO:0005506    iron ion binding    Interacting selectively and non-covalently with iron (Fe) ions.
    GO:0004872    receptor activity    Combining with an extracellular or intracellular messenger to initiate a change in cell activity.
    GO:0015344    siderophore uptake transmembrane transporter activity    Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: siderophore-iron(ferrioxamine)(out) + H+(out) = siderophore-iron(ferrioxamine)(in) + H+(in).
    GO:0015643    toxic substance binding    Interacting selectively and non-covalently with a toxic substance, a poisonous substance that causes damage to biological systems.
    GO:0046790    virion binding    Interacting selectively and non-covalently with a virion, either by binding to components of the capsid or the viral envelope.
biological process
    GO:0006811    ion transport    The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0055072    iron ion homeostasis    Any process involved in the maintenance of an internal steady state of iron ions within an organism or cell.
    GO:0044718    siderophore transmembrane transport    The directed movement of siderophores, low molecular weight Fe(III)-chelating substances, from one side of a membrane to the other, by means of some agent such as a transporter or pore.
    GO:0015891    siderophore transport    The directed movement of siderophores, low molecular weight Fe(III)-chelating substances, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0009279    cell outer membrane    A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures.
