| | 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. |
| | GO:0015478 | | oligosaccharide transporting porin activity | | Catalysis of the transfer of oligosaccharide, 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: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. |
| biological process |
|---|
| | GO:0034219 | | carbohydrate transmembrane transport | | The process in which a carbohydrate is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. |
| | GO:0006811 | | ion transport | | The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| | GO:0015768 | | maltose transport | | The directed movement of maltose into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the catabolism of glycogen and starch. |
| | GO:0015772 | | oligosaccharide transport | | The directed movement of oligosaccharides into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Oligosaccharides are molecules with between two and (about) 20 monosaccharide residues connected by glycosidic linkages. |
| | GO:0006810 | | transport | | The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein. |
| cellular component |
|---|
| | GO:0009279 | | cell outer membrane | | A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures. |
| | GO:0045203 | | integral component of cell outer membrane | | The component of the cell outer membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| | GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0046930 | | pore complex | | Any small opening in a membrane that allows the passage of gases and/or liquids. |
