| GO:0022857 | transmembrane transporter activity | Enables the transfer of a substance from one side of a membrane to the other. |
| GO:0022891 | substrate-specific transmembrane transporter activity | Enables the transfer of a specific substance or group of related substances from one side of a membrane to the other. |
| GO:0005215 | transporter activity | Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. |
| GO:0003674 | 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: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:0015288 | porin activity | Catalysis of the transfer of substances, sized less than 1000 Da, from one side of the membrane to the other. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria. |
| GO:0022803 | passive transmembrane transporter activity | Enables the transfer of a solute from one side of the membrane to the other, down the solute's concentration gradient. |
| GO:0022829 | wide pore channel activity | Enables the transport of a solute across a membrane via a large pore, un-gated channel. Examples include gap junctions, which transport substances from one cell to another; and porins which transport substances in and out of bacteria, mitochondria and chloroplasts. |
| GO:0015267 | channel activity | Enables the energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. |
| 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:0005363 | maltose transmembrane transporter activity | Enables the transfer of maltose from one side of the membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch. |
| GO:0015154 | disaccharide transmembrane transporter activity | Enables the transfer of disaccharide from one side of the membrane to the other. |
| GO:0015157 | oligosaccharide transmembrane transporter activity | Enables the transfer of oligosaccharide from one side of the membrane to the other. |
| GO:0015481 | maltose transporting porin activity | Catalysis of the transfer of maltose from one side of the membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch. This transporter is a porin so enables the energy independent passage of substances, sized less than 1000 Da, across a membrane. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria. |
