Ascorbate peroxidase activity of cytochromec
Free Radical Research, 2010 The peroxidase-type reactivity of cytochrome c is proposed to play a role in free radical production and/or apoptosis. This study describes cytochrome c catalysis of peroxide consumption by ascorbate.

Novel insight into functions of ascorbate peroxidase in higher plants: More than a simple antioxidant enzyme. [PDF]
Redox Biol, 2023 As plants are sessile organisms, they are inevitably exposed to a variety of environmental stimuli that trigger rapid changes in the generation and disposal of reactive oxygen species such as hydrogen peroxide (H2O2).

Antioxidant Response in the Salt-Acclimated Red Beet (Beta vulgaris) Callus
Agronomy, 2023 Callus cultures initiated from red beet tubers were acclimated to 75 or 100 mM NaCl salinity by exposing them to gradually increasing NaCl concentrations.

Engineering the active site of ascorbate peroxidase [PDF]
European Journal of Biochemistry, 2001 The oxidation of a number of thioethers, namely methyl phenyl sulphide (1), ethyl phenyl sulphide (2), isopropyl phenyl sulphide (3), n‐propyl phenyl sulphide (4), p‐chlorophenyl methyl sulphide (5), p‐nitrophenyl methyl sulphide (6) and methyl naphthalene sulphide (7), by recombinant pea cytosolic ascorbate peroxidase (rAPX) and a site‐directed ...

Ascorbate Peroxidase cDNA from Maize [PDF]
Plant Physiology, 1995 APx (EC 1.11.1.11) is a heme-containing, nonglycosylated enzyme that destroys harmful hydrogen peroxide via the ascorbate-glutathione pathway in plants. This pathway provides protection against oxidative stress by a series of coupled redox reactions, particularly in photosynthetic tissues (Foyer and Halliwell, 1976).

The Effect of Exogenous Application of Gibberellic Acid and Girdling on Characters of Grapes (Vitis vinifera) cv. Yaghoot [PDF]
Journal of Genetic Resources, 2022 ‘Yaghoot’ grape cultivar is the earliest cultivar known in the history of Iran. The main problem of this cultivar is the compactness and small size of its berries, under the influenced genes that are controlled mainly by Gibberellic Acid (GA3).

Ascorbate is the natural substrate for plant peroxidases [PDF]
FEBS Letters, 1996 Ascorbate‐dependent detoxification of hydrogen peroxide by guaiacol‐type peroxidases is increased considerably in the presence of 3,4‐dihydroxyphenolic compounds, suggesting that ascorbate is the natural substrate for many types of peroxidase in situ and not just the ascorbate‐specific peroxidases.

Triazine Probes Target Ascorbate Peroxidases in Plants [PDF]
Plant Physiology, 2019 Though they are rare in nature, anthropogenic 1,3,5-triazines have been used in herbicides as chemically stable scaffolds. Here, we show that small 1,3,5-triazines selectively target ascorbate peroxidases (APXs) in Arabidopsis (Arabidopsis thaliana), tomato (Solanum lycopersicum), rice (Oryza sativa), maize (Zea mays), liverwort (Marchantia polymorpha),
