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:0000250|UniProtKB:P38013}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[thioredoxin]-dithiol + a hydroperoxide = [thioredoxin]-
CC         disulfide + an alcohol + H2O; Xref=Rhea:RHEA:62620, Rhea:RHEA-

CC         Evidence={ECO:0000250|UniProtKB:P38013};
CC   -!- SUBUNIT: Homodimer; disulfide-linked, upon oxidation.
CC       {ECO:0000250|UniProtKB:P38013}.
CC   -!- ALLERGEN: Causes an allergic reaction in human.
CC       {ECO:0000269|PubMed:9675120}.
CC   -!- MISCELLANEOUS: The active site is a conserved redox-active cysteine
CC       residue, the peroxidatic cysteine (C(P)), which makes the nucleophilic
CC       attack on the peroxide substrate. The peroxide oxidizes the C(P)-SH to
CC       cysteine sulfenic acid (C(P)-SOH), which then reacts with another
CC       cysteine residue, the resolving cysteine (C(R)), to form a disulfide
CC       bridge. The disulfide is subsequently reduced by an appropriate
CC       electron donor to complete the catalytic cycle. In this typical 2-Cys
CC       Prx, C(R) is provided by the other dimeric subunit to form an
CC       intersubunit disulfide. The disulfide is subsequently reduced by
CC       thioredoxin. {ECO:0000250|UniProtKB:P38013}.
CC   -!- SIMILARITY: Belongs to the peroxiredoxin family. Prx5 subfamily.
CC       {ECO:0000305}.
