| molecular function |

| | GO:0005507 | | copper ion binding | | Interacting selectively and non-covalently with copper (Cu) ions. |
| | GO:0009486 | | cytochrome bo3 ubiquinol oxidase activity | | Catalysis of the reaction: 2 ubiquinol + O2 + 4 H+ = 2 ubiquinone + 2 H2O + 4 H+ [periplasmic space]. |
| | GO:0008827 | | cytochrome o ubiquinol oxidase activity | | Catalysis of the reaction: ubiquinol + O2 = ubiquinone + 2 H2O; cytochrome O is the electron acceptor. |
| | GO:0004129 | | cytochrome-c oxidase activity | | Catalysis of the reaction: 4 ferrocytochrome c + O2 + 4 H+ = 4 ferricytochrome c + 2 H2O. |
| | 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:0015078 | | hydrogen ion transmembrane transporter activity | | Enables the transfer of hydrogen ions from one side of a membrane to the other. |
| | 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:0016682 | | oxidoreductase activity, acting on diphenols and related substances as donors, oxygen 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 oxygen. |
| | GO:0015453 | | oxidoreduction-driven active transmembrane transporter activity | | Primary active transport of a solute across a membrane, driven by exothermic flow of electrons from a reduced substrate to an oxidized substrate. Primary active transport is catalysis of the transport of a solute across a membrane, up the solute's concentration gradient, by binding the solute and undergoing a series of conformational changes. Transport works equally well in either direction and is driven by a primary energy source. |
| | GO:0048039 | | ubiquinone binding | | Interacting selectively and non-covalently with ubiquinone, a quinone derivative with a tail of isoprene units. |
| biological process |
|---|
| | GO:0019646 | | aerobic electron transport chain | | A process in which a series of electron carriers operate together to transfer electrons from donors such as NADH and FADH2 to oxygen to generate a transmembrane electrochemical gradient. |
| | GO:0009060 | | aerobic respiration | | The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor. |
| | GO:0022900 | | electron transport chain | | 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:0015990 | | electron transport coupled proton transport | | The transport of protons against an electrochemical gradient, using energy from electron transport. |
| | GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| cellular component |
|---|
| | GO:0009319 | | cytochrome o ubiquinol oxidase complex | | A protein complex that possesses cytochrome o ubiquinol oxidase activity; consists of four polypeptide subunits and associated prosthetic groups. |
| | GO:0071575 | | integral component of external side of plasma membrane | | The component of the plasma membrane consisting of the gene products that penetrate only the external side of the membrane. |
| | GO:0016021 | | integral component of membrane | | 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. |
| | GO:0005887 | | integral component of plasma membrane | | The component of the plasma 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. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| | GO:0070469 | | respiratory chain | | The protein complexes that form the electron transport system (the respiratory chain), associated with a cell membrane, usually the plasma membrane (in prokaryotes) or the inner mitochondrial membrane (on eukaryotes). The respiratory chain complexes transfer electrons from an electron donor to an electron acceptor and are associated with a proton pump to create a transmembrane electrochemical gradient. |
