Status: annotated
Amino acids: 187
Structure source: AlphaFold + ColabFold

1.11.1.26

GO:0016491 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:0006979 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:0051920 Catalysis of the reaction: [protein]-dithol + ROOH = [protein]-disulfide + H2O + ROH. GO:0016209 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:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. GO:0102039 Catalysis of the reaction: a hydroperoxide + H+ + NADH = an alcohol + H2O + NAD+.
