GO
GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. GO:0015848 The directed movement of spermidine, N-(3-aminopropyl)-1,4-diaminobutane, a polyamine formed by the transfer of a propylamine group from decarboxylated S-adenosylmethionine to putrescine, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0022857 Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0015606 Enables the transfer of spermidine, N-(3-aminopropyl)-1,4-diaminobutane, from one side of a membrane to the other. GO:0015199 Enables the transfer of betaine from one side of a membrane to the other. Betaine is the N-trimethyl derivative of an amino acid.

  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0015848 The directed movement of spermidine, N-(3-aminopropyl)-1,4-diaminobutane, a polyamine formed by the transfer of a propylamine group from decarboxylated S-adenosylmethionine to putrescine, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

  • GO:0015199 Enables the transfer of betaine from one side of a membrane to the other. Betaine is the N-trimethyl derivative of an amino acid.
  • GO:0015297 Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. The reaction is: solute A(out) + solute B(in) = solute A(in) + solute B(out).
  • GO:0015220 Enables the transfer of choline from one side of a membrane to the other. Choline (2-hydroxyethyltrimethylammonium) is an amino alcohol that occurs widely in living organisms as a constituent of certain types of phospholipids and in the neurotransmitter acetylcholine.
  • GO:0031460 The directed movement of glycine betaine, N-trimethylglycine, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:1990961 A process that reduces or removes the toxicity of a xenobiotic by exporting it outside the cell.
