Light-Controlled Tyrosine Nitration of Proteins
Angewandte Chemie - International Edition, 2021Abstract Tyrosine nitration of proteins is one of the most important oxidative post‐translational modifications in vivo. A major obstacle for its biochemical and physiological studies is the lack of efficient and chemoselective protein tyrosine nitration reagents. Herein, we report a generalizable strategy for light‐controlled protein

Protein Tyrosine Nitration—An Update
Archives of Biochemistry and Biophysics, 2009Tyrosine nitration is a covalent post-translational protein modification derived from the reaction of proteins with nitrating agents. Tyrosine nitration has been used as a marker of oxidant burden in human diseases. However, it remains unclear whether protein nitration is responsible for alterations in protein function that imparts an increased risk ...

Protein tyrosine nitration (PTN) is a selective post-translational modification often associated with pathophysiological conditions. Although yeast cells lack of mammalian nitric oxide synthase (NOS) orthologues, still it has been shown that they are capable of producing nitric oxide (NO).

Mitochondrial protein tyrosine nitration
Free Radical Research, 2010Mitochondria are primary loci for the intracellular formation and reactions of reactive oxygen and nitrogen species including superoxide (O₂•⁻), hydrogen peroxide (H₂O₂) and peroxynitrite (ONOO⁻). Depending on formation rates and steady-state levels, the mitochondrial-derived short-lived reactive species contribute to signalling events and/or ...

Mitochondria and regulated tyrosine nitration
Biochemical Society Transactions, 2005The conditions of the cellular microenvironment in complex multicellular organisms fluctuate, enforcing permanent adaptation of cells at multiple regulatory levels. Covalent post-translational modifications of proteins provide the short-term response tools for cellular adjustment and growing evidence supports the possibility that protein tyrosine ...

Protein tyrosine nitration (PTN) is a post-translational modification occurring under the action of a nitrating agent. Tyrosine is modified in the 3-position of the phenolic ring through the addition of a nitro group (NO2). In the present article, we review the main nitration reactions and elucidate why nitration is not a random chemical process.

Enrichment and Detection of Tyrosine‐Nitrated Proteins
Current Protocols in Protein Science, 2012AbstractNitrotyrosine is a post‐translationally modified amino acid with distinctly different properties than tyrosine or any other of the genetically encoded amino acids. Detecting proteins containing nitrotyrosine is the first step towards a better understanding of the role of nitrotyrosine in health and disease.

Protein Tyrosine Nitration in Atherosclerotic Endothelial Dysfunction
Clinica Chimica Acta, 2022Accumulation of reactive oxygen species (ROS) can induce both protein tyrosine nitration and endothelial dysfunction in atherosclerosis. Endothelial dysfunction refers to impaired endothelium-dependent vasorelaxation that can be triggered by an imbalance in nitric oxide (NO) production and consumption.

Protein Tyrosine Nitration: Role in Aging
Current Aging Science, 2017Aging is the inevitable fate of all living organisms, but the molecular basis of physiological aging is poorly understood. Oxidative stress is believed to play a key role in the aging process. In addition to Reactive Oxygen Species (ROS), Reactive Nitrogen Species (RNS) are generated during aerobic metabolism in living organisms.
