6 GO

Gene Ontology (GO)

6
  • 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:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other.
  • 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:0015489 Enables the transfer of putrescine from one side of a membrane to the other. Putrescine is 1,4-diaminobutane, the polyamine formed by decarboxylation of ornithine and the metabolic precursor of spermidine and spermine.
  • GO:0015295 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: solute(out) + H+(out) = solute(in) + H+(in).

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

76 records

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
