Protein

Peroxiredoxin TSA1

Gene

TSA1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Physiologically important antioxidant which constitutes an enzymatic defense against sulfur-containing radicals. Can provide protection against a thiol-containing oxidation system but not against an oxidation system without thiol.

Catalytic activityi

2 R'-SH + ROOH = R'-S-S-R' + H2O + ROH.

Post-translational modificationi

The Cys-48-SH group is the primary site of oxidation by H2O2, and the oxidized Cys-48 (probably Cys-SOH) rapidly reacts with Cys-171-SH of the other subunit to form an intermolecular disulfide. This disulfide is subsequently reduced by thioredoxin.
Forms a transient disulfide bond with SRX1 during the reduction of cysteine sulfinic acid (-SO2H).
