Free radicals and other active derivatives of oxygen are inevitable by-products of biological
redox reactions. Reactive oxygen species inactivate enzymes and damage important …

The thiol group of cysteine (Cys) residues, often present in the active center of the protein, is
of particular importance to protein function, which is significantly determined by the redox …

Superoxide dismutases (SODs) are a family of metalloenzymes that catalyze the dismutation
or disproportionation of superoxide radicals (O _ 2^ ⋅-O 2·-) into molecular oxygen (O 2) …

Peroxisomes are subcellular organelles with an essentially oxidative type of metabolism.
Like chloroplasts and mitochondria, plant peroxisomes also produce superoxide radicals () …

The evolution of photosynthesis and its associated metabolic pathways has been crucial to
the successful establishment of plants, but has also challenged plant cells in the form of …

Plant peroxisomes are organelles enclosed by a single membrane whose biochemical
composition has the capacity to adapt depending on the plant tissue, developmental stage …

Although peroxisomes are very simple organelles, research on different species has
provided us with an understanding of their importance in terms of cell viability. In addition to …

Senescence is a genetically regulated oxidative process that involves a general degradation
of the cellular structures and enzymes and the mobilization of the products of degradation to …

The presence of nitric-oxide synthase (NOS) in peroxisomes from leaves of pea plants
(Pisum sativum L.) was studied. Plant organelles were purified by differential and sucrose …

The activities of the ascorbate‐glutathione cycle enzymes ascorbate peroxidase (APX),
