CC -!- FUNCTION: Thiol-specific peroxidase that catalyzes the reduction of
CC hydrogen peroxide and organic hydroperoxides to water and alcohols,
CC respectively. {ECO:0000256|PIRNR:PIRNR000239}.
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 ChEBI:CHEBI:29950, ChEBI:CHEBI:30879, ChEBI:CHEBI:35924,

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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
