General annotation (Comments)
| Function | Thiol-specific antioxidant protein with alkyl hydroperoxidase activity. Involved in osmotic stress resistance and detoxification of the cell. Preferentially eliminates organic peroxides rather than H2O2. Involved in cellular Mn2+ homeostasis. |
| Catalytic activity | 2 R'-SH + ROOH = R'-S-S-R' + H2O + ROH. |
| Subunit structure | Homodimer; disulfide-linked, upon oxidation. Ref.5 |
| Subcellular location | |
| Induction | By H2O2. Ref.9 |
| Post-translational modification | The Cys-62-SH group is the primary site of oxidation by H2O2, and the oxidized Cys-62 (probably Cys-SOH) rapidly reacts with Cys-120-SH of the other subunit to form an intermolecular disulfide. This disulfide is subsequently reduced by thioredoxin to restore the reduced active form of the enzyme. Conjugated to URM1, an ubiquitin-like protein. |
| Miscellaneous | Present with 16228 molecules/cell in log phase SD medium. Ref.14 |
| Sequence similarities | Belongs to the peroxiredoxin 2 family. Contains 1 thioredoxin domain. |
| Biophysicochemical properties | Kinetic parameters: KM=150 µM for H2O2 KM=45 µM for cumene hydroperoxide KM=8 µM for tert-butyl hydroperoxide KM=3 µM for TRX1 KM=2 µM for TRX2 Vmax=20 µmol/min/mg enzyme for H2O2 Vmax=17 µmol/min/mg enzyme for cumene hydroperoxide Vmax=14 µmol/min/mg enzyme for tert-butyl hydroperoxide Vmax=17 µmol/min/mg enzyme for TRX1 Vmax=16 µmol/min/mg enzyme for TRX2 pH dependence: Optimum pH is 6.5. |
