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. Preferentially eliminates organic peroxides rather
CC       than hydrogen peroxide (PubMed:10391912, PubMed:9988687,
CC       PubMed:10681558). Relays alkyl hydroperoxides as a signal to the
CC       transcription factor CAD1/YAP2 by inducing the formation of
CC       intramolecular disulfide bonds in CAD1, which causes its nuclear
CC       accumulation and activation (PubMed:20145245). Involved in cellular
CC       Mn(2+) homeostasis (PubMed:10635552). {ECO:0000269|PubMed:10391912,

CC       {ECO:0000269|PubMed:14555475, ECO:0000269|PubMed:21209336}.
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:0000305|PubMed:22474296}.
CC   -!- MISCELLANEOUS: Present with 16228 molecules/cell in log phase SD
CC       medium. {ECO:0000269|PubMed:14562106}.
CC   -!- SIMILARITY: Belongs to the peroxiredoxin family. Prx5 subfamily.
CC       {ECO:0000305}.
CC   -!- CAUTION: Biochemical and mutational analysis assigned Cys-120 as the
CC       resolving cysteine (C(R)) (PubMed:9888818). However, crystal structures
CC       showed that Cys-120 is deeply buried within the protein and revealed
CC       formation of a disulfide bond between the peroxidatic cysteine Cys-62
CC       and the therefore more likely C(R) Cys-31 (PubMed:22474296, Ref.21).
