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 COMP:10698, Rhea:RHEA-COMP:10700, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:29950, ChEBI:CHEBI:30879, ChEBI:CHEBI:35924,
CC ChEBI:CHEBI:50058; EC=1.11.1.24;
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.
CC {ECO:0000313|EMBL:PTE23481.1}.
