Dinitrosyliron complexes and the mechanism(s) of cellular protein nitrosothiol formation from nitric oxide.
Nitrosothiols (RSNO), formed from thiols and metabolites of nitric oxide (*NO), have been implicated in a diverse set of physiological and pathophysiological processes, although the exact mechanisms by which they are formed biologically are unknown. Several candidate nitrosative pathways involve the reaction of *NO with O(2), reactive oxygen species (ROS), and transition metals. We developed a ...
متن کاملNitric oxide-induced conversion of cellular chelatable iron into macromolecule-bound paramagnetic dinitrosyliron complexes.
One of the most important biological reactions of nitric oxide (nitrogen monoxide, *NO) is its reaction with transition metals, of which iron is the major target. This is confirmed by the ubiquitous formation of EPR-detectable g=2.04 signals in cells, tissues, and animals upon exposure to both exogenous and endogenous *NO. The source of the iron for these dinitrosyliron complexes (DNIC), and it...

15 صفحه اولPerspective Series: Nitric Oxide and Nitric Oxide Synthases Cellular and Molecular Mechanisms of Endothelial Cell Dysfunction
The clinical relevance of the vascular L -arginine/nitric oxide (NO) 1 synthase system to vascular biology lies in the oftrepeated observation that it is altered by a variety of pathophysiological conditions. Such alterations of NO production and/or bioavailability have been shown to occur both in experimental animal models and in human subjects, in the setting of such diverse disorders as hype...
متن کاملReciprocal regulation of cellular nitric oxide formation by nitric oxide synthase and nitrite reductases
Our mini-review focuses on dual regulation of cellular nitric oxide (NO) signaling pathways by traditionally characterized enzymatic formation from L-arginine via the actions of NO synthases (NOS) and by enzymatic reduction of available cellular nitrite pools by a diverse class of cytosolic and mitochondrial nitrite reductases. Nitrite is a major metabolic product of NO and is found in all cell...
