Mechanism of the Reaction of Peroxynitrite with Mn-Superoxide Dismutase: Nitration of Critical Tyrosine-34

Manganese superoxide dismutase (MnSOD) is an antioxidantenzyme that acts as a superoxide detoxifier. Superoxide can reactwith nitric oxide to lead peroxynitrite and this reaction, that takesplace at near diffusion limited rates, can compete with MnSOD forsuperoxide. One of the most important bio-mar...

Descripción
Sumario:Manganese superoxide dismutase (MnSOD) is an antioxidantenzyme that acts as a superoxide detoxifier. Superoxide can reactwith nitric oxide to lead peroxynitrite and this reaction, that takesplace at near diffusion limited rates, can compete with MnSOD forsuperoxide. One of the most important bio-markers forperoxynitrite formation in vivo is tyrosine nitration, a posttranslationalmodification that can alter both the structure andfunction of a protein.
