Ascorbate Peroxidase Neofunctionalization at the Origin of APX-R and APX-L: Evidence from Basal Archaeplastida [PDF]
Antioxidants, 2021 Ascorbate peroxidases (APX) are class I members of the Peroxidase-Catalase superfamily, a large group of evolutionarily related but rather divergent enzymes.

Genome-wide, evolutionary, and functional analyses of ascorbate peroxidase (APX) family in Poaceae species [PDF]
Genetics and Molecular Biology, 2022 Ascorbate peroxidases (APXs) are heme peroxidases involved in the control of hydrogen peroxide levels and signal transduction pathways related to development and stress responses.

Measurement of Ascorbate Peroxidase Activity in Sorghum
Bio-Protocol, 2022 The ascorbate peroxidase (APX) is a widely distributed antioxidant enzyme. It differs from catalase and other peroxidases in that it scavenges/reduces reactive oxygen species (ROS) such as hydrogen peroxide (H2O2) to water using reduced ascorbate as the ...

Ascorbate Peroxidase 2 (APX2) of Chlamydomonas Binds Copper and Modulates the Copper Insertion into Plastocyanin [PDF]
Antioxidants, 2023 Recent phylogenetic studies have unveiled a novel class of ascorbate peroxidases called “ascorbate peroxidase-related” (APX-R). These enzymes, found in green photosynthetic eukaryotes, lack the amino acids necessary for ascorbate binding.

Catalase and Ascorbate Peroxidase in Euglenozoan Protists [PDF]
Pathogens, 2020 In this work, we studied the biochemical properties and evolutionary histories of catalase (CAT) and ascorbate peroxidase (APX), two central enzymes of reactive oxygen species detoxification, across the highly diverse clade Eugenozoa.

Arabidopsis APx-R Is a Plastidial Ascorbate-Independent Peroxidase Regulated by Photomorphogenesis
Antioxidants, 2021 Peroxidases are enzymes that catalyze the reduction of hydrogen peroxide, thus minimizing cell injury and modulating signaling pathways as response to this reactive oxygen species.

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.

Biologia Plantarum, 2012 An ascorbate-deficient semi-dwarf mutant asfL-1 was detected in 250 Gy γ-ray treated grass pea (Lathyrus sativus L.) cv. BioR-231. The mutant contained only 42 % of leaf and 20 % of root ascorbate content of mother control (MC).
