|
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). |

|
molecular_function
|
Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
GO:0022890
|
inorganic cation transmembrane transporter activity
|
Enables the transfer of inorganic cations from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. |
GO:0022892
|
substrate-specific transporter activity
|
Enables the directed movement of a specific substance or group of related substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. |
GO:0022804
|
active transmembrane transporter activity
|
Catalysis of the transfer of a specific substance or related group of substances from one side of a membrane to the other, up the solute's concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction. |
GO:0015291
|
secondary active transmembrane transporter activity
|
Catalysis of the transfer of a solute from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy, not direct ATP coupling. Chemiosmotic sources of energy include uniport, symport or antiport. |
GO:0015077
|
monovalent inorganic cation transmembrane transporter activity
|
Enables the transfer of a inorganic cations with a valency of one from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. |
GO:0015081
|
sodium ion transmembrane transporter activity
|
Enables the transfer of sodium ions (Na+) from one side of a membrane to the other. |
GO:0015298
|
solute: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: solute(out) + cation(in) = solute(in) + cation(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). |
