| Identifier | Name | Description |
|---|---|---|
| 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: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:0015075 | ion transmembrane transporter activity | Enables the transfer of an ion from one side of a membrane to the other. |
| 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: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: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:0022838 | substrate-specific channel activity | Enables the energy-independent facilitated diffusion, mediated by passage of a specific 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:0034290 | holin activity | A compound function consisting of the regulated formation of a pore via oligomerisation of an existing pool of subunits in the plasma membrane. The resulting channel activity directly or indirectly allows murein hydrolyases to access their cell wall substrate. |
| GO:0034292 | pinholin activity | A compound function consisting of the regulated formation of a pore via oligomerisation of an existing pool of subunits in the plasma membrane. The resulting ion channel activity indirectly allows endolysin (murein hydrolyases) to access their cell wall substrate by collapsing the proton motive force (PMF) across the membrane, allowing the endolysin to fold to an active form and hydrolyze bonds in the peptidoglycan cell wall. |
