[GOC:mlg] EOG822D2B GO:0006979 2/7 response to oxidative stress biological_process "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." [GOC:jl, PMID:12115731] EOG822D2B GO:0033743 2/7 peptide-methionine (R)-S-oxide reductase activity molecular_function "Catalysis of the reaction: peptide-L-methionine + H(2)O + thioredoxin disulfide = peptide-L-methionine (R)-S-oxide + thioredoxin. Can act on oxidized methionine in peptide linkage with specificity for the R enantiomer. Thioredoxin disulfide is the oxidized form of thioredoxin." [EC:1.8.4.12, GOC:mah, GOC:vw, RHEA:24167]
