Dual regulation of cytosolic ascorbate peroxidase (APX) by tyrosine nitration and S-nitrosylation
Post-translational modifications (PTMs) mediated by nitric oxide (NO)-derived molecules have become a new area of research, as they can modulate the function of target proteins. Proteomic data have shown that ascorbate peroxidase (APX) is one of the potential targets of PTMs mediated by NO-derived molecules. Using recombinant pea cytosolic APX, the impact of peroxynitrite (ONOO-) and S-nitrosog...
متن کاملCytosolic ascorbate peroxidase 1 is a central component of the reactive oxygen gene network of Arabidopsis.
Reactive oxygen species (ROS), such as O2- and H2O2, play a key role in plant metabolism, cellular signaling, and defense. In leaf cells, the chloroplast is considered to be a focal point of ROS metabolism. It is a major producer of O2- and H2O2 during photosynthesis, and it contains a large array of ROS-scavenging mechanisms that have been extensively studied. By contrast, the function of the ...
متن کاملThe TL29 protein is lumen located, associated with PSII and not an ascorbate peroxidase.
The TL29 protein is one of the more abundant proteins in the thylakoid lumen of plant chloroplasts. Based on its sequence homology to ascorbate peroxidases, but without any supporting biochemical evidence, TL29 was suggested to be involved in the plant defense system against reactive oxygen species and consequently renamed to APX4. Our in vivo and in vitro analyses failed to show any peroxidase...
متن کاملWireless Communication Is in APX
In this paper we address a common question in wireless communication: How long does it take to satisfy an arbitrary set of wireless communication requests? This problem is known as the wireless scheduling problem. Our main result proves that wireless scheduling is in APX. In addition we present a robustness result, showing that constant parameter and model changes will modify the result only by...
متن کاملAscorbate peroxidase from soybean root nodules.
AP is involved in the destruction of harmful H202. In soybean (Glycine m a x [LI Merr.) root nodules, AP initiates a sequence of coupled redox reactions (ascorbate-GSH pathway) that results in peroxide scavenging (Dalton et al., 1986). The ascorbate-GSH pathway occurs in other plant tissues and has been extensively studied in chloroplasts where photoreducing conditions lead to the production of...
