The H2O2 byproduct of fatty acid catabolism in plant peroxisomes is removed in part by a
membrane‐associated antioxidant system that involves both an ascorbate peroxidase and a …

In plant cells, ascorbate is a major antioxidant that is involved in the ascorbate-glutathione
cycle. Monodehydroascorbate reductase (MDAR) is the enzymatic component of this cycle …

In higher plants, peroxisomes have been believed to play a pivotal role in three metabolic
pathways, which are lipid breakdown, photorespiration and H2O2-detoxificaton. Recently …

Peroxisomes are vital organelles that compartmentalize critical metabolic reactions, such as
the breakdown of fats, in eukaryotic cells. Although peroxisomes typically are considered to …

Hydrogen peroxide is a major by-product of peroxisomal metabolism and has the potential
to cause critical oxidative damage. In all eukaryotes, catalase is thought to be instrumental in …

Monodehydroascorbate reductase (MDAR) is an enzyme involved in ascorbate recycling.
Arabidopsis thaliana has five MDAR genes that encode two cytosolic, one …

Peroxisomes are globular organelles, of approximately 1μm in diameter, that are found
ubiquitously in eukaryotic cells. In higher plants, peroxisomes have been believed to play a …

The peroxisomal isoform of ascorbate peroxidase (APX) is a novel membrane isoform that
functions in the regeneration of NAD+ and protection against toxic reactive oxygen species …

Previously we reported (RT Mullen, CS Lisenbee, JA Miernyk, RN Trelease Plant Cell 11:
2167–2185) that overexpressed ascorbate peroxidase (APX), a peroxisomal membrane …

Peroxisomes, one of single membrane‐bound organelles, are present ubiquitously in
eukaryotic cells. They were originally identified as organelles for production of hydrogen …
