Gene Ontology (GO)

6
  • 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:0005295 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: neutral L-amino acid(out) + Na+(out) = neutral L-amino acid(in) + Na+(in).
  • GO:0032329 The directed movement of L-serine, 2-amino-3-hydroxypropanoic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0015826 The directed movement of threonine, (2R*,3S*)-2-amino-3-hydroxybutanoic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
  • GO:0015293 Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.

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.

82 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.
