In addition to uncoupling, peroxynitrite formation can also occur when levels of nitric oxide are so high that superoxide dismutase is overcome and can no longer provide dismutation activity (Vinten-Johansen, 2000).

Per oxynitrite, is this the "gorilla in the room" we have been missing: how you can finally control peroxynitrite by supporting genetic variants

Copper is present in a large number of enzymes, which are involved in electron transfer, activation of oxygen, and other small molecules as well as superoxide dismutation [1, 2].

The enzyme superoxide dismutase catalyzes the dismutation of superoxide into oxygen and hydrogen peroxide.

Anti-inflammatory effect of Emblica officinalis in rodent models of acute and chronic inflammation: involvement of possible mechanisms

Superoxide dismutase activity of all these complexes has been revealed to catalyze the dismutation of superoxide ([O.sub.2.sup.-]), and [IC.sub.50] values were evaluated and discussed.

Synthesis, electrochemical, spectroscopic, antimicrobial, and superoxide dismutase activity of nickel (II) complexes with bidentate Schiff bases

Superoxide anion can also undergo dismutation to form hydrogen peroxide ([H.sub.2][O.sub.2]), either spontaneously or when catalyzed by the enzyme superoxide dismutase (27).

(12), (19-23) In other words, [Ce.sup.4+] was present in the form of Ce[(OH).sub.2.sup.2+] in the solution, resulting from the oxidization of Ce[(OH).sub.3] in alkaline solution; then the Ce[(OH).sub.3] was converted into Ce[0.sub.2] in a dismutation solid state reaction.

(6) Superoxide dismutase, which catalyses the dismutation of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is considered to be the essential enzyme in the defense against the toxic effects of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII].

Glutathione reductase, reduced glutathione and ceruloplasmin in diethyldithiocarbamate treated rats

Induction of nNOS/iNOS by methamphetamine or MDMA (Figure 3) constitutes part of the mechanism of methamphetamine damage, as selective inhibition or genetic inactivation of nNOS and overexpression of cupper zinc superoxide dismutase (CuZnSOD), an enzyme that catalyzes the dismutation of superoxide into oxygen and hydrogen peroxide, prevent methamphetamine neurotoxicity [23, 37, 38].
