| GO term | GO name | GO namespace | GO def |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0016491 | oxidoreductase activity | molecular_function | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. [GOC:go_curators] |
| GO:0046872 | metal ion binding | molecular_function | Binding to a metal ion. [GOC:ai] |
| GO:0022804 | active transmembrane transporter activity | molecular_function | Enables the transfer of a specific substance or related group of substances from one side of a membrane to the other, up the solute's concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction. [GOC:mtg_transport, ISBN:0815340729] |
| GO:0020037 | heme binding | molecular_function | Binding to a heme, a compound composed of iron complexed in a porphyrin (tetrapyrrole) ring. [GOC:ai] |
| GO:0022857 | transmembrane transporter activity | molecular_function | 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. [GOC:jid, GOC:mtg_transport, ISBN:0815340729] |
| GO:0055085 | transmembrane transport | biological_process | The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. [GOC:dph, GOC:jid] |
| GO:0005215 | transporter activity | molecular_function | Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. [GOC:ai, GOC:dgf] |
| GO:0003824 | catalytic activity | molecular_function | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

| GO:0016021 | integral component of membrane | cellular_component | 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. [GOC:dos, GOC:go_curators] |
