Chain A,B   (NHAA_ECOLI | P13738)
molecular function
    GO:0015297    antiporter activity    Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. The reaction is: solute A(out) + solute B(in) = solute A(in) + solute B(out).
    GO:0015491    cation:cation antiporter activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: cation A(out) + cation B(in) = cation A(in) + cation B(out).
    GO:0015081    sodium ion transmembrane transporter activity    Enables the transfer of sodium ions (Na+) from one side of a membrane to the other.
biological process
    GO:0098655    cation transmembrane transport    A process in which a cation is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    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:0015992    proton transport    The directed movement of protons (hydrogen ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0006885    regulation of pH    Any process involved in the maintenance of an internal equilibrium of hydrogen ions, thereby modulating the internal pH, within an organism or cell.
    GO:0035725    sodium ion transmembrane transport    A process in which a sodium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    GO:0006814    sodium ion transport    The directed movement of sodium ions (Na+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0055085    transmembrane transport    The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
    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: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:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    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.
