Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Nitrosative Stress Stimulus. Nitrosative Stress Is a State Often Resulting From Exposure to High Levels of Nitric Oxide (no) or the Highly Reactive Oxidant Peroxynitrite Which Is Produced Following Interaction of No with Superoxide Anions.
Catalysis of an Oxidation Reduction (redox) Reaction a Reversible Chemical Reaction in Which the Oxidation State of an Atom or Atoms Within a Molecule Is Altered. One Substrate Acts As a Hydrogen or Electron Donor and Becomes Oxidized While the Other Acts As Hydrogen or Electron Acceptor and Becomes Reduced.
