molecular function |
| GO:0004602 | | glutathione peroxidase activity | | Catalysis of the reaction: 2 glutathione + hydrogen peroxide = oxidized glutathione + 2 H2O. |
| 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:0098869 | | cellular oxidant detoxification | | Any process carried out at the cellular level that reduces or removes the toxicity superoxide radicals or hydrogen peroxide. |
| 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: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. |
