Extracellular superoxide dismutase

The International Journal of Biochemistry & Cell Biology, 2005
The extracellular space is protected from oxidant stress by the antioxidant enzyme extracellular superoxide dismutase (EC-SOD), which is highly expressed in selected tissues including blood vessels, heart, lungs, kidney and placenta. EC-SOD contains a unique heparin-binding domain at its carboxy-terminus that establishes localization to the ...

SUPEROXIDE RADICAL AND SUPEROXIDE DISMUTASES

Annual Review of Biochemistry, 1972
O2- 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 ...

Superoxide, Superoxide Dismutase and the Respiratory Burst

Veterinary Clinical Pathology, 1983
SummaryPhagocytes 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 ...

[10] Superoxide dismutase assays

1984
Publisher Summary The primary difficulty in assaying Superoxide dismutase (SOD) for its enzymatic activity consists in the free radical nature of its substrate O 2 · - which can only be supplied by generation within the assay medium. The substrate O 2 · - cannot easily be detected directly by conventional analytical tools.

Superoxide dismutases in Eimeria tenella

Molecular and Biochemical Parasitology, 1991
Unsporulated oocysts of Eimeria tenella have high superoxide dismutase (SOD: superoxide:superoxide oxidoreductase, EC 1.15.1.1.) activity and contain several electrophoretically distinct forms of the enzyme, including two forms of Cu/Zn-containing SOD, two forms of Fe-SOD and two forms of Mn-SOD. SOD activity remains high during 12 h of sporulation but

Polarographic determination of superoxide dismutase

Analytical Biochemistry, 1975
Abstract A polarographic procedure is described which allows determination of the catalytic constants for superoxide dismutase-catalyzed reactions. The method presents a single and rapid evaluation of the enzyme concentrations as well as determination of its activity under different conditions; e.g., pH between 9 and 13, presence of urea, guanidine ...
