A review on the oxidative and nitrosative stress (O&NS) pathways in major depression and their possible contribution to the (neuro)degenerative processes in that illness. (2011, background): “Catalase is a very common enzyme that catalyzes the reduction of hydrogen peroxide to water and oxygen and mediates signalling in cell proliferation, apoptosis, carbohydrate metabolism, and platelet activation (Chelikani et al., 2004; Góth et al., 2004).”
Nrf2 and Oxidative Stress: A General Overview of Mechanisms and Implications in Human Disease (2022, background): “Catalase is found in nearly all living eukaryotic organisms and exists primarily within peroxisomes as well as in the mitochondria and nucleus [33].”
Catalase function in plants: a focus on Arabidopsis mutants as stress-mimic models. (2010, background): “In this organelle, H2O2 can be formed directly from O2 by photorespiratory glycolate oxidase (Foyer et al., 2009) or by other enzyme systems such as xanthine oxidase coupled to superoxide dismutase (del Rı́o et al., 2006; Corpas et al., 2008).”
First line defence antioxidants-superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX): Their fundamental role in the entire antioxidant defence grid (2018, background): “A second hydrogen peroxide molecule acts as a reducing agent to regenerate the resting state enzyme, producing a molecule of oxygen and water.(36) Hydrogen peroxide though at low amounts tends to regulate some physiological processes such as signaling in cell proliferation, cell death, carbohydrate ”
Exercise-Induced Oxidative Stress: Cellular Mechanisms and Impact on Muscle Force Production (2008, background): “a required cofactor attached to the active site of the enzyme (64, 206, 416).”
Cell signaling mechanisms and metabolic regulation of germination and dormancy in barley seeds (2017, background): “6), which transforms H2O2 into H2O and O2 [111], are the important enzymes for detoxifying ROS.”
Free radicals, antioxidants and functional foods: Impact on human health (2010, background): “[52] Hydrogen peroxide is a harmful by-product of many normal metabolic processes: to prevent damage, it must be quickly converted into other, less dangerous substances.”
