| GO:0016688 | | L-ascorbate peroxidase activity | | Catalysis of the reaction: L-ascorbate + hydrogen peroxide = dehydroascorbate + 2 H2O. |
| GO:0004129 | | cytochrome-c oxidase activity | | Catalysis of the reaction: 4 ferrocytochrome c + O2 + 4 H+ = 4 ferricytochrome c + 2 H2O. |
| GO:0020037 | | heme binding | | Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring. |
| GO:0004447 | | iodide peroxidase activity | | Catalysis of the reaction: iodide + hydrogen peroxide = iodine + 2 H2O. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| 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:0004601 | | peroxidase activity | | Catalysis of the reaction: donor + hydrogen peroxide = oxidized donor + 2 H2O. |
biological process |
| GO:0055074 | | calcium ion homeostasis | | Any process involved in the maintenance of an internal steady state of calcium ions within an organism or cell. |
| GO:0098869 | | cellular oxidant detoxification | | Any process carried out at the cellular level that reduces or removes the toxicity superoxide radicals or hydrogen peroxide. |
| GO:1902600 | | hydrogen ion transmembrane transport | | The directed movement of hydrogen ion (proton) across a membrane. |
| GO:0042744 | | hydrogen peroxide catabolic process | | The chemical reactions and pathways resulting in the breakdown of hydrogen peroxide (H2O2). |
| GO:0043066 | | negative regulation of apoptotic process | | Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process. |
| 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. |
| GO:0072593 | | reactive oxygen species metabolic process | | The chemical reactions and pathways involving a reactive oxygen species, any molecules or ions formed by the incomplete one-electron reduction of oxygen. They contribute to the microbicidal activity of phagocytes, regulation of signal transduction and gene expression, and the oxidative damage to biopolymers. |
| GO:0042493 | | response to drug | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease. |
| GO:0006979 | | response to oxidative stress | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals. |
| GO:0000302 | | response to reactive oxygen species | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a reactive oxygen species stimulus. Reactive oxygen species include singlet oxygen, superoxide, and oxygen free radicals. |
| GO:0030322 | | stabilization of membrane potential | | The accomplishment of a non-fluctuating membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. |
cellular component |
| GO:0005783 | | endoplasmic reticulum | | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
| GO:0031304 | | intrinsic component of mitochondrial inner membrane | | The component of the mitochondrial inner membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane. |
