Comments
Comment typeDescription
Catalytic Activity2 glutathione + a lipid hydroperoxide = glutathione disulfide + lipid + 2 H(2)O.
FunctionProtects cells and enzymes from oxidative damage, by catalyzing the reduction of hydrogen peroxide, lipid peroxides and organic hydroperoxide, by glutathione. {ECO:0000250}.
InductionBy salt stress, osmotic stress, metals and heat treatment. Up-regulated by abscisic acid (ABA) and auxin. {ECO:0000269|PubMed:14617062}.
SimilarityBelongs to the glutathione peroxidase family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast stroma {ECO:0000269|PubMed:12766230}.
Tissue SpecificityExpressed in leaves, stems, flowers, green siliques and seeds. {ECO:0000269|PubMed:14617062}.
