Recovery of reduced thiol groups by superoxide-mediated denitrosation of nitrosothiols

open access: yesRedox Biology, 2022
Nitrosation of critical thiols has been elaborated as reversible posttranslational modification with regulatory function in multiple disorders. Reversibility of S-nitrosation is generally associated with enzyme-mediated one-electron reductions, catalyzed

Nitric oxide destabilizes Pias3 and regulates sumoylation. [PDF]

open access: yesPLoS ONE, 2007
Small ubiquitin-related protein modifiers (SUMO) modification is an important mechanism for posttranslational regulation of protein function. However, it is largely unknown how the sumoylation pathway is regulated.

Soluble guanylyl cyclase mediates noncanonical nitric oxide signaling by nitrosothiol transfer under oxidative stress

open access: yesRedox Biology, 2022
Soluble guanylyl cyclase (GC1) is an α/β heterodimer producing cGMP when stimulated by nitric oxide (NO). The NO-GC1-cGMP pathway is essential for cardiovascular homeostasis but is disrupted by oxidative stress, which causes GC1 desensitization to NO by ...

S-Nitrosation: Current Concepts and New Developments [PDF]

open access: yesAntioxidants & Redox Signaling, 2012
The S-nitrosation (also referred to as S-nitrosylation) of cysteine residues is an important post-translational protein modification that regulates protein function and cell signaling. The original research articles and reviews in this Forum cover important concepts in protein S-nitrosation and identify key developments and opportunities for progress ...

Novel Tocolytic Strategy: Modulating Cx43 Activity by <i>S</i>-Nitrosation. [PDF]

open access: yesJ Pharmacol Exp Ther, 2021
Currently available tocolytics are ineffective at significantly delaying preterm birth. This is due in part to our failure to better understand the mechanisms that drive spontaneous preterm labor (sPTL). Cyclic nucleotides are not the primary contributors to myometrial quiescence, but instead nitric oxide (NO)-mediated protein S-nitrosation (SNO) is ...

Detailed mechanistic investigation into the S-nitrosation of cysteamine [PDF]

open access: yesCanadian Journal of Chemistry, 2012
The nitrosation of cysteamine (H2NCH2CH2SH) to produce cysteamine-S-nitrosothiol (CANO) was studied in slightly acidic medium by using nitrous acid prepared in situ. The stoichiometry of the reaction was H2NCH2CH2SH + HNO2 → H2NCH2CH2SNO + H2O.

Focus on Nitric Oxide Homeostasis: Direct and Indirect Enzymatic Regulation of Protein Denitrosation Reactions in Plants

open access: yesAntioxidants, 2022
Protein cysteines (Cys) undergo a multitude of different reactive oxygen species (ROS), reactive sulfur species (RSS), and/or reactive nitrogen species (RNS)-derived modifications.

S-Nitrosation of Cellular Proteins by NO Donors in Rat Embryonic Fibroblast 3Y1 Cells: Factors Affecting S-Nitrosation [PDF]

open access: yesOxidative Medicine and Cellular Longevity, 2011
The mechanism of protein S-nitrosation in cells is not fully understood. Using rat 3Y1 cells, we addressed this issue. Among S-nitrosothiols and NO donors tested, only S-nitrosocysteine (CysNO) induced S-nitrosation when exposed in Hanks' balanced salt solution (HBSS) and not in serum-containing general culture medium.

HIF‐1α protein as a target for S‐nitrosation

open access: yesFEBS Letters, 2003
Hypoxia‐inducible factor‐1α (HIF‐1α) is a master regulator to sense decreased oxygen partial pressure. HIF‐1α stability regulation initiates a complex biological response that allows cells to act appropriately to meet patho‐physiological situations of decreased oxygen availability.

Tomato Root Growth Inhibition by Salinity and Cadmium Is Mediated By S-Nitrosative Modifications of ROS Metabolic Enzymes Controlled by S-Nitrosoglutathione Reductase

open access: yesBiomolecules, 2019
S-nitrosoglutathione reductase (GSNOR) exerts crucial roles in the homeostasis of nitric oxide (NO) and reactive nitrogen species (RNS) in plant cells through indirect control of S-nitrosation, an important protein post-translational modification in ...
