Nitration of the egg-allergen ovalbumin enhances protein allergenicity but reduces the risk for oral sensitization in a murine model of food allergy.

PLoS ONE, 2010
BackgroundNitration of proteins on tyrosine residues, which can occur due to polluted air under "summer smog" conditions, has been shown to increase the allergic potential of allergens.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Biochemistry of protein tyrosine nitration in cardiovascular pathology [PDF]

Cardiovascular Research, 2007
Several pathologies of the cardiovascular system are associated with an augmented production of nitric oxide and/or superoxide-derived oxidants and/or alteration in the antioxidant detoxification pathways that lead to nitroxidative stress. One important consequence of these reactive intermediates at the biochemical level is the nitration of protein ...

Underground Signals: The Ecological Power of Root Volatiles

Advanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

Antioxidant promotion of tyrosine nitration in the presence of copper(II).

, 2013
Copper(II) is known to catalyze the generation of reactive nitrogen species in the presence of hydrogen peroxide, nitrite or nitric oxide, leading to tyrosine nitration, a biomarker for free radical species associated diseases.

Global changes in nitration levels and DNA binding profile of Trypanosoma cruzi histones induced by incubation with host extracellular matrix.

PLoS Neglected Tropical Diseases, 2020
Adhesion of T. cruzi trypomastigotes to components of the extracellular matrix (ECM) is an important step in mammalian host cell invasion. We have recently described a significant increase in the tyrosine nitration levels of histones H2A and H4 when ...

Evidence for the Prerequisite Formation of Phenoxyl Radicals in Radical‐Mediated Peptide Tyrosine Nitration In Vacuo

, 2020
The elementary mechanism of radical‐mediated peptide tyrosine nitration, which is a hallmark of post‐translational modification of proteins under nitrative stress in vivo, has been elucidated in detail by using an integrated approach that combines the ...
