CC -!- FUNCTION: Thiol-specific peroxidase that catalyzes the reduction of
CC hydrogen peroxide and organic hydroperoxides to water and alcohols,
CC respectively. Plays a role in cell protection against oxidative stress
CC by detoxifying peroxides. {ECO:0000256|RuleBase:RU366011}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a hydroperoxide + 2 glutathione = an alcohol + glutathione
CC disulfide + H2O; Xref=Rhea:RHEA:62632, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:30879, ChEBI:CHEBI:35924, ChEBI:CHEBI:57925,
CC ChEBI:CHEBI:58297; EC=1.11.1.27;
CC Evidence={ECO:0000256|RuleBase:RU366011};
CC -!- SIMILARITY: Belongs to the peroxiredoxin family. Prx5 subfamily.
CC {ECO:0000256|RuleBase:RU366011}.
