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. Also involved in the correct composition of the
CC hyphal cell wall. {ECO:0000269|PubMed:16102003}.
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:0000250|UniProtKB:P34760};
CC -!- SUBUNIT: Homodimer; disulfide-linked, upon oxidation.
CC {ECO:0000250|UniProtKB:P34760}.
CC -!- SUBCELLULAR LOCATION: Cell surface {ECO:0000269|PubMed:16102003}.
CC Nucleus {ECO:0000269|PubMed:16134099}. Cytoplasm
CC {ECO:0000269|PubMed:16134099}. Note=Localizes to the cell surface in
CC hyphally grown cells, whereas no surface but mainly nuclear
CC localization is found in yeast-form cells.
CC {ECO:0000269|PubMed:16102003}.
CC -!- INDUCTION: Induced by oxidative stress. {ECO:0000269|PubMed:16102003}.
CC -!- DISRUPTION PHENOTYPE: Results in delayed hyphal development and
CC enhanced sensitivity to cell wall-perturbing agents, yet does not
CC impair virulence in vivo. {ECO:0000269|PubMed:16102003}.
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 peroxiredoxin, 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:P34760}.
CC -!- SIMILARITY: Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
CC {ECO:0000305}.
