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 and as sensor of hydrogen peroxide-mediated
CC signaling events. Might participate in the signaling cascades of growth
CC factors and tumor necrosis factor-alpha by regulating the intracellular
CC concentrations of H(2)O(2). {ECO:0000256|ARBA:ARBA00037127}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-dithiol + a hydroperoxide = [thioredoxin]-
CC disulfide + an alcohol + H2O; Xref=Rhea:RHEA:62620, Rhea:RHEA-
CC COMP:10698, Rhea:RHEA-COMP:10700, ChEBI:CHEBI:15377,

CC Evidence={ECO:0000256|ARBA:ARBA00000280,
CC ECO:0000256|PIRNR:PIRNR000239};
CC -!- SIMILARITY: Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
CC {ECO:0000256|ARBA:ARBA00009796}.
