The Millisecond Intermediate in the Reaction of Nitric Oxide with Oxymyoglobin is an Iron(III)−Nitrato Complex, Not a Peroxynitrite

DOI: 10.1021/ja9026924 Authors: Erik T. Yukl, Simon de Vries, Pierre Moënne‐Loccoz Abstract: The dioxygenation of nitric oxide by oxyheme in globin proteins is a major route for NO detoxification in aerobic biological systems. In myoglobin, this reaction is thought to...
