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:0009055
|
electron carrier activity
|
Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient. |
|
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:0004129
|
cytochrome-c oxidase activity
|
Catalysis of the reaction: 4 ferrocytochrome c + O2 + 4 H+ = 4 ferricytochrome c + 2 H2O. |
|
GO:0015002
|
heme-copper terminal oxidase activity
|
Catalysis of the four-electron reduction of dioxygen (O2) to water, coupled to generation of a proton electrochemical gradient across a membrane. |
|
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:0016676
|
oxidoreductase activity, acting on a heme group of donors, oxygen as acceptor
|
Catalysis of an oxidation-reduction (redox) reaction in which a heme group acts as a hydrogen or electron donor and reduces oxygen. |
|
GO:0016675
|
oxidoreductase activity, acting on a heme group of donors
|
Catalysis of an oxidation-reduction (redox) reaction in which a heme group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor. |
