Superoxide, Superoxide Dismutase and the Respiratory Burst
Veterinary Clinical Pathology, 1983SummaryPhagocytes undergo a sharp burst of oxygen consumption when engulfing bacteria. This oxygen is enzymatically reduced to toxic metabolites which are essential to the bactericidal action of the cell. Oxygen metabolites formed in this burst as well as other intermediates formed in biological reduction reactions do not selectively reserve their ...

The Reaction of no With Superoxide
Free Radical Research Communications, 1993The rate constant for the reaction of NO with .O2- was determined to be (6.7 +/- 0.9) x 10(9) l mol-1 s-1, considerably higher than previously reported. Rate measurements were made from pH 5.6 to 12.5 both by monitoring the loss of .O2- and the formation of the product -OONO.

SUPEROXIDE RADICAL AND SUPEROXIDE DISMUTASES
Annual Review of Biochemistry, 1972O2- oxidizes the [4Fe-4S] clusters of dehydratases, such as aconitase, causing-inactivation and release of Fe(II), which may then reduce H2O2 to OH- +OH.. SODs inhibit such HO. production by scavengingO2-, but Cu, ZnSODs, by virtue of a nonspecific peroxidase activity, may peroxidize spin trapping agents and thus give the appearance of catalyzing OH ...

The Journal of Physical Chemistry B, 2005
Density-functional calculations indicate that the second sphere of coordination around the metal centers of manganese and iron superoxide dismutases (MnSODs and FeSODs) plays an important role in the binding of O2(-). In these systems, O2(-) prefers to bind to Mn or Fe in end-on configurations. For human and E.
