RL Sci. Rep. 8:8058-8058(2018).
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. {ECO:0000256|RuleBase:RU366011}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[glutaredoxin]-dithiol + a hydroperoxide = [glutaredoxin]-
CC disulfide + an alcohol + H2O; Xref=Rhea:RHEA:62624, Rhea:RHEA-
CC COMP:10729, Rhea:RHEA-COMP:10730, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:29950, ChEBI:CHEBI:30879, ChEBI:CHEBI:35924,
CC ChEBI:CHEBI:50058; EC=1.11.1.25;
CC Evidence={ECO:0000256|ARBA:ARBA00001711};
CC -!- SIMILARITY: Belongs to the peroxiredoxin family. Prx5 subfamily.
CC {ECO:0000256|ARBA:ARBA00010505, ECO:0000256|RuleBase:RU366011}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
