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:RU366004}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a hydroperoxide + H(+) + NADH = an alcohol + H2O + NAD(+);
CC Xref=Rhea:RHEA:62628, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC Evidence={ECO:0000256|ARBA:ARBA00000318,
CC ECO:0000256|RuleBase:RU366004};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|RuleBase:RU366004}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|RuleBase:RU366004}.
CC -!- SIMILARITY: Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
