|
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. |

|
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. |

Enables the transfer of sodium ions (Na+) from one side of a membrane to the other. |
|
GO:0015293
|
symporter activity
|
Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. |
|
GO:0015294
|
solute:cation symporter 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(out) = solute(in) + cation(in). |
|
GO:0005402
|
cation:sugar symporter activity
|
Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: sugar(out) + cation(out) = sugar(in) + cation(in). |
|
GO:0015144
|
carbohydrate transmembrane transporter activity
|
Enables the transfer of carbohydrate from one side of the membrane to the other. |
|
GO:0051119
|
sugar transmembrane transporter activity
|
Catalysis of the transfer of a sugar from one side of the membrane to the other. A sugar is any member of a class of sweet, water-soluble, crystallizable carbohydrates, which are the monosaccharides and smaller oligosaccharides. |
|
GO:1901476
|
carbohydrate transporter activity
|
Enables the directed movement of carbohydrate into, out of or within a cell, or between cells. |
|
GO:0015154
