RT "Complete sequence of Shewanella frigidimarina NCIMB 400.";
RL Submitted (AUG-2006) to the EMBL/GenBank/DDBJ databases.
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|ARBA:ARBA00037420}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a hydroperoxide + H(+) + NADH = an alcohol + H2O + NAD(+);
CC Xref=Rhea:RHEA:62628, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30879, ChEBI:CHEBI:35924, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57945; EC=1.11.1.26;
CC Evidence={ECO:0000256|ARBA:ARBA00000318};
CC -!- SIMILARITY: Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
CC {ECO:0000256|ARBA:ARBA00009796}.
