GO
GO:0015288 Enables the transfer of substances, sized less than 1000 Da, from one side of a 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:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0034219 The process in which a carbohydrate is transported across a membrane. GO:0009279 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:0046930 A protein complex providing a discrete opening in a membrane that allows the passage of gases and/or liquids. GO:0015144 Enables the transfer of carbohydrate from one side of a membrane to the other.

  • GO:0015144 Enables the transfer of carbohydrate from one side of a membrane to the other.
  • GO:0006811 The directed movement of a monoatomic ion into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Monatomic ions (also called simple ions) are ions consisting of exactly one atom.
  • GO:0015774 The directed movement of polysaccharides into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. A polysaccharide is a polymer of many (typically more than 10) monosaccharide residues linked glycosidically.
