Glutathione (2011, neutral): “In Arabidopsis cat2 knockouts, DHAR2 (At1g75270), which is predicted to encode a cytosolic enzyme, is induced along with cytosolic APX1 (At1g07890; Mhamdi et al., 2010a).”
Aluminum toxicity in plant cells: Mechanisms of cell death and inhibition of cell elongation (2018, background): “Superoxide is reduced to H2O2 by dismutation spontaneously or enzymatically by SOD, and then H2O2 is scavenged by several antioxidant systems, including ascorbate peroxidase, glutathione peroxidase, peroxiredoxins, and catalases (Mhamdi et al. 2010).”
The Roles of Reactive Oxygen Metabolism in Drought: Not So Cut and Dried[1][C][W] (2014, background): “Vol. 164, 2014 apparent in CAT-deficient mutants, in which oxidative signaling linked to photorespiration is forced through thiol-based pathways (Mhamdi et al., 2010), causing marked changes in cell thiol-disulfide status that have been shown to be required for increased oxidation to activate…”
Glutathione Is a Key Player in Metal-Induced Oxidative Stress Defenses (2012, background): “This GSSG compartmentalization may play a role in helping to maintain a reduced cytosolic GSH redox status, implying that plant cells are configured to limit large changes in the cytosolic (and possibly nuclear) GSH redox potentials [46,151,176,177].”
Molecular Mechanism of Heavy Metal Toxicity and Tolerance in Plants: Central Role of Glutathione in Detoxification of Reactive Oxygen Species and Methylglyoxal and in Heavy Metal Chelation (2012, background): “Plasma membrane-bound NADPH oxidases as well as cellwall associated peroxidases are the main sources of O2 •− and H2O2 producing apoplastic enzymes [205].”
Reactive Oxygen Species, Oxidative Damage, and Antioxidative Defense Mechanism in Plants under Stressful Conditions (2012, neutral): “Though there are frequent reports of CAT being present in cytosol, chloroplast, and mitochondria, the presence of significant CAT activity in these is less well established [186].”
Antioxidant Enzyme Activities and Gene Expression Patterns in Leaves of Kentucky Bluegrass in Response to Drought and Post-drought Recovery (2011, background): “CAT enzymes are mostly localized in peroxisomes (Fridovich, 1978; Mhamdi et al., 2010) with the exception of CAT-3 from maize (Zea mays), which is mitochondrial (Scandalios et al., 1980).”
Research Advances in Mechanisms of Turfgrass Tolerance to Abiotic Stresses: From Physiology to Molecular Biology (2014, background): “Catalases break hydrogen peroxide into water and oxygen, which are mostly localized in peroxisomes (Mhamdi et al., 2010).”
