The redox properties of ascorbate peroxidase
Biochemistry, 2007 Reduction potentials for the catalytic compound I/compound II and compound II/Fe3+ redox couples, and for the two-electron compound I/Fe 3+ redox couple, have been determined for ascorbate peroxidase (APX) and for a number of site-directed variants.

Cytosolic ascorbate peroxidase in Gymnosperms
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2000 Sixteen species of Gymnosperms have been screened for cytosolic ascorbate peroxidase by means of native polyacrylamide gel electrophoresis. This analysis shows that a single form of the enzyme is the most common situation.

Plant ascorbate peroxidase: molecular phylogeny and role in oxidative stress
Studia Universitatis Babeș-Bolyai. Biologia, 2018 Oxidative stress appears as a condition in accumulation and detoxification of reactive oxygen species (ROS). ROS are oxygen-derived free radicals, generated predominantly in mitochondria, peroxisomes and chloroplasts, as natural byproducts of the normal ...

Abolishing activity against ascorbate in a cytosolic ascorbate peroxidase from switchgrass
Phytochemistry, 2013 Switchgrass (Panicum virgatum L.) is being developed as a bioenergy species. Recently an early version of its genome has been released permitting a route to the cloning and analysis of key proteins.

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.

Abiotic Stress Tolerance in Plants: Myriad Roles of Ascorbate Peroxidase [PDF]
Frontiers in Plant Science, 2017 One of the most significant manifestations of environmental stress in plants is the increased production of Reactive Oxygen Species (ROS). These ROS, if allowed to accumulate unchecked, can lead to cellular toxicity. A battery of antioxidant molecules is

Activity of Cytosolic Ascorbate Peroxidase (APX) from Panicum virgatum against Ascorbate and Phenylpropanoids. [PDF]
Int J Mol Sci, 2023 APX is a key antioxidant enzyme in higher plants, scavenging H2O2 with ascorbate in several cellular compartments. Here, we report the crystal structures of cytosolic ascorbate peroxidase from switchgrass (Panicum virgatum L., Pvi), a strategic feedstock

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 ...

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).

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).
