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. {ECO:0000256|ARBA:ARBA00003330}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[thioredoxin]-dithiol + a hydroperoxide = [thioredoxin]-
CC         disulfide + an alcohol + H2O; Xref=Rhea:RHEA:62620, Rhea:RHEA-

CC         Evidence={ECO:0000256|ARBA:ARBA00000280};
CC   -!- SUBUNIT: Monomer. {ECO:0000256|ARBA:ARBA00011245}.
CC   -!- SIMILARITY: Belongs to the peroxiredoxin family. BCP/PrxQ subfamily.
CC       {ECO:0000256|ARBA:ARBA00038489}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
