| molecular function |
|---|
| | GO:0016209 | | antioxidant activity | | Inhibition of the reactions brought about by dioxygen (O2) or peroxides. Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radicals, thereby breaking the chain reaction that normally leads to extensive biological damage. |
| | GO:0005507 | | copper ion binding | | Interacting selectively and non-covalently with copper (Cu) ions. |
| | 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:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| | GO:0004784 | | superoxide dismutase activity | | Catalysis of the reaction: 2 superoxide + 2 H+ = O2 + hydrogen peroxide. |
| | GO:0008270 | | zinc ion binding | | Interacting selectively and non-covalently with zinc (Zn) ions. |
| biological process |
|---|
| | GO:0001320 | | age-dependent response to reactive oxygen species involved in chronological cell aging | | 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.) occurring in non-dividing cells as they age as a result of reactive oxygen species, where the change varies according to the age of the cell or organism. |
| | GO:0006878 | | cellular copper ion homeostasis | | Any process involved in the maintenance of an internal steady state of copper ions at the level of a 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:0006882 | | cellular zinc ion homeostasis | | Any process involved in the maintenance of an internal steady state of zinc ions at the level of a cell. |
| | GO:0031505 | | fungal-type cell wall organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the fungal-type cell wall. |
| | GO:1901856 | | negative regulation of cellular respiration | | Any process that stops, prevents or reduces the frequency, rate or extent of cellular respiration. |
| | 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:0051091 | | positive regulation of DNA-binding transcription factor activity | | Any process that activates or increases the frequency, rate or extent of activity of a transcription factor, any factor involved in the initiation or regulation of transcription. |
| | GO:0036091 | | positive regulation of transcription from RNA polymerase II promoter in response to oxidative stress | | Any process that increases the frequency, rate or extent of transcription from an RNA polymerase II promoter as a result of a stimulus indicating the organism is under 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:0050821 | | protein stabilization | | Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation. |
| | GO:0019430 | | removal of superoxide radicals | | Any process, acting at the cellular level, involved in removing superoxide radicals (O2-) from a cell or organism, e.g. by conversion to dioxygen (O2) and hydrogen peroxide (H2O2). |
| | GO:0006801 | | superoxide metabolic process | | The chemical reactions and pathways involving superoxide, the superoxide anion O2- (superoxide free radical), or any compound containing this species. |
| cellular component |
|---|
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0005758 | | mitochondrial intermembrane space | | The region between the inner and outer lipid bilayers of the mitochondrial envelope. |
| | GO:0005739 | | mitochondrion | | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. |
| | GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
