CC       Mitochondrion outer membrane; Peripheral membrane protein
CC       {ECO:0000269|PubMed:22659048}.
CC   -!- INDUCTION: By glucose starvation. {ECO:0000269|PubMed:10480913}.
CC   -!- DISRUPTION PHENOTYPE: Impairs growth and peroxisome formation in oleic
CC       acid medium. {ECO:0000269|PubMed:22659048}.
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 atypical 2-Cys
CC       peroxiredoxin, C(R) is present in the same subunit to form an
CC       intramolecular disulfide. {ECO:0000305|PubMed:20572871}.
CC   -!- SIMILARITY: Belongs to the glutathione peroxidase family.
CC       {ECO:0000305}.
CC   -!- CAUTION: Was originally thought to be a glutathione peroxidase
CC       (PubMed:10480913) or a phospholipid hydroperoxide glutathione
CC       peroxidase (PubMed:11445588), but functions as an atypical 2-Cys
CC       peroxiredoxin using both glutathione and thioredoxin almost equally as
CC       reducing power instead (PubMed:20572871). {ECO:0000305|PubMed:10480913,
CC       ECO:0000305|PubMed:11445588, ECO:0000305|PubMed:20572871}.
