Redox regulation of proteasome function
Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) were initially regarded mainly as metabolic by-products with damaging properties. Over the last decade, our understanding of their role in metabolism was drastically changed and they were recognized as essential mediators in cellular signaling cascades, as well as modulators of biochemical pathways. Proteostasis is highly affecte...
متن کاملRedox regulation of plant homeodomain transcription factors.
Several families of plant transcription factors contain a conserved DNA binding motif known as the homeodomain. In two of these families, named Hd-Zip and glabra2, the homeodomain is associated with a leucine zipper-like dimerization motif. A group of Hd-Zip proteins, namely Hd-ZipII, contain a set of conserved cysteines within the dimerization motif and adjacent to it. Incubation of one of the...
متن کاملRedox regulation of auxin signaling and plant development in Arabidopsis.
Thioredoxin (NTR/TRX) and glutathione (GSH/GRX) are the two major systems which play a key role in the maintenance of cellular redox homeostasis. They are essential for plant development, cell division or the response to environmental stresses. In a recent article, we studied the interplay between the NADP-linked thioredoxin and glutathione systems in auxin signaling genetically, by associating...
متن کاملThe function of peroxiredoxins in plant organelle redox metabolism.
In 1996, cDNA sequences referred to as plant peroxiredoxins (Prx), i.e. a 1-Cys Prx and a 2-Cys Prx, were reported from barley. Ten years of research have advanced our understanding of plant Prx as thiol-based peroxide reductases with a broad substrate specificity, ranging from hydrogen peroxide to alkyl hydroperoxides and peroxinitrite. Prx have several features in common. (i) They are abundan...
متن کاملPlant chitinases--regulation and function.
The aim of this review is to present the current state of knowledge on plant chitinases and their regulation and function. Chitinases are up-regulated by a variety of stress conditions, both biotic and abiotic, and by such phytohormones as ethylene, jasmonic acid, and salicylic acid. Like other PR proteins, chitinases play a role in plant resistance against distinct pathogens. Moreover, by redu...
