Chain A,B,C,D,E,F   (CLCA_ECOLI | P37019)
molecular function
    GO:0043168    anion binding    Interacting selectively and non-covalently with anions, charged atoms or groups of atoms with a net negative charge.
    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:0031404    chloride ion binding    Interacting selectively and non-covalently with chloride ions (Cl-).
    GO:0015108    chloride transmembrane transporter activity    Enables the transfer of chloride ions from one side of a membrane to the other.
    GO:0005216    ion channel activity    Enables the facilitated diffusion of an ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. May be either selective (it enables passage of a specific ion only) or non-selective (it enables passage of two or more ions of same charge but different size).
    GO:0015299    solute:proton antiporter activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: solute(out) + H+(in) = solute(in) + H+(out).
    GO:0005247    voltage-gated chloride channel activity    Enables the transmembrane transfer of a chloride ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
biological process
    GO:1902476    chloride transmembrane transport    The directed movement of chloride across a membrane.
    GO:0006821    chloride transport    The directed movement of chloride into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:1902600    hydrogen ion transmembrane transport    The directed movement of hydrogen ion (proton) across a membrane.
    GO:0034220    ion transmembrane transport    A process in which an ion 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:0015706    nitrate transport    The directed movement of nitrate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:1903959    regulation of anion transmembrane transport    Any process that modulates the frequency, rate or extent of anion transmembrane transport.
    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:0005887    integral component of plasma membrane    The component of the plasma 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.
