GO Term : GO:0000269 toxin export channel activity GO

Namespace:  molecular_function Obsolete:  false
description  Enables the energy independent passage of toxins, sized less than 1000 Da, across a membrane towards the outside of the cell. 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:0006810 transport The directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or pore.
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:0022857 transmembrane transporter activity Enables the transfer of a substance 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: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: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:0009987 cellular process Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
GO:0044763 single-organism cellular process Any process that is carried out at the cellular level, occurring within a single organism.
GO:0044699 single-organism process A biological process that involves only one organism.
GO:0051179 localization Any process in which a cell, a substance, or a cellular entity, such as a protein complex or organelle, is transported to or maintained in a specific location.
GO:1902578 single-organism localization A localization which involves only one organism.
GO:0008150 biological_process Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
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:0051234 establishment of localization The directed movement of a cell, substance or cellular entity, such as a protein complex or organelle, to a specific location.
GO:0044765 single-organism transport The directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or pore, involving a single organism.
GO:0019534 toxin transporter activity Enables the directed movement of a toxin into, out of or within a cell, or between cells. A toxin is a poisonous compound (typically a protein) that is produced by cells or organisms and that can cause disease when introduced into the body or tissues of an organism.
GO:0000269 toxin export channel activity Enables the energy independent passage of toxins, sized less than 1000 Da, across a membrane towards the outside of the cell.

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:1901998 toxin transport The directed movement of a toxin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
