Protein attributes
| Sequence length | 213 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Exhibits glutathione-dependent thiol transferase and dehydroascorbate (DHA) reductase activities. Key component of the ascorbate recycling system. Involved in the redox homeostasis, especially in scavenging of ROS under oxidative stresses. Plays a role in ozone tolerance. Ref.8 |
| Catalytic activity | RX + glutathione = HX + R-S-glutathione. |
| Subunit structure | Monomer By similarity. |
| Subcellular location | |
| Induction | By ozone. By salicylic acid (SA) (at protein level). Ref.7 Ref.8 |
| Post-translational modification | Spontaneous S-glutathionylation in the presence of oxidized glutathione (GSSG). |
| Disruption phenotype | Mutant develops distinct foliar lesions under ozone exposure. Ref.8 |
| Sequence similarities | Belongs to the GST superfamily. DHAR family. Contains 1 GST C-terminal domain. Contains 1 GST N-terminal domain. |
