Cytosolic Ascorbate Peroxidases Plays a Critical Role in Photosynthesis by Modulating Reactive Oxygen Species Level in Stomatal Guard Cell [PDF]
Frontiers in Plant Science, 2020 Photosynthetic rate is one of the key factors limiting yield of cotton. Reactive oxygen species (ROS) generated by abiotic stress imposes numerous detrimental effects and causes tremendous loss of yield.

The ascorbate peroxidase–related protein: insights into its functioning in Chlamydomonas and Arabidopsis [PDF]
Frontiers in Plant ScienceWe review the newly classified ascorbate peroxidase–related (APX-R) proteins, which do not use ascorbate as electron donor to scavenge H2O2. We summarize recent discoveries on the function and the characterization of the APX-R protein of the green ...

Comparative analysis of ascorbate peroxidases (APXs) from selected plants with a special focus on Oryza sativa employing public databases. [PDF]
PLoS ONE, 2019 Reactive oxygen species (ROS) are produced by plants. Hydrogen peroxide (H2O2) is one important component of ROS and able to modulate plant growth and development at low level and damage plant cells at high concentrations.

An enzymatic cascade enables sensitive and specific proximity labeling proteomics in challenging biological systems [PDF]
Nature CommunicationsAscorbate peroxidase (APEX) is a proximity labeling enzyme used for subcellular proteomics at high spatial and temporal resolution. However, toxicity of its substrate hydrogen peroxide and background labeling by endogenous peroxidases limit its use to in

Affinity of class I and class III peroxidases for H2O2 in pepper leaves of different maturity [PDF]
Kragujevac Journal of Science, 2021 Paper deals with activities of Class III peroxidases (POX, EC 1.11.1.7) and Class I peroxidases (ascorbate peroxidase, APX, EC 1.11.1.11) as well as the Km of these enzymes for hydrogen peroxide (H2O2) in the pepper leaves of different maturity.
