Identifier Name Description
GO:0016491 oxidoreductase activity 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.
GO:0003824 catalytic activity 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:0022857 transmembrane transporter activity Enables the transfer of a substance from one side of a membrane to the other.
GO:0022891 substrate-specific transmembrane transporter activity Enables the transfer of a specific substance or group of related substances from one side of a membrane to the other.
GO:0005215 transporter activity Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
GO:0008324 cation transmembrane transporter activity Enables the transfer of cation from one side of the membrane to the other.
GO:0015078 hydrogen ion transmembrane transporter activity Enables the transfer of hydrogen ions from one side of a membrane to the other.
GO:0008121 ubiquinol-cytochrome-c reductase activity Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: CoQH2 + 2 ferricytochrome c = CoQ + 2 ferrocytochrome c + 2 H+.
GO:0016679 oxidoreductase activity, acting on diphenols and related substances as donors Catalysis of an oxidation-reduction (redox) reaction in which a diphenol or related substance acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.
GO:0015075 ion transmembrane transporter activity Enables the transfer of an ion from one side of a membrane to the other.
GO:0003674 molecular_function Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions.
GO:0022890 inorganic cation transmembrane transporter activity Enables the transfer of inorganic cations from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage.
GO:0022892 substrate-specific transporter activity Enables the directed movement of a specific substance or group of related substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
GO:0015077 monovalent inorganic cation transmembrane transporter activity Enables the transfer of a inorganic cations with a valency of one from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage.
GO:0016681 oxidoreductase activity, acting on diphenols and related substances as donors, cytochrome as acceptor Catalysis of an oxidation-reduction (redox) reaction in which a diphenol, or related compound, acts as a hydrogen or electron donor and reduces a cytochrome.
