Extracellular superoxide dismutase
The International Journal of Biochemistry & Cell Biology, 2005The 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, 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 ...

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 ...

Superoxide dismutases in Eimeria tenella
Molecular and Biochemical Parasitology, 1991Unsporulated 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

Science, 1999
The copper chaperone for the superoxide dismutase (CCS) gene is necessary for expression of an active, copper-bound form of superoxide dismutase (SOD1) in vivo in spite of the high affinity of SOD1 for copper (dissociation constant = 6 fM) and the high ...

Polarographic determination of superoxide dismutase
Analytical Biochemistry, 1975Abstract 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 ...

Microbial Superoxide Dismutases
1989Publisher Summary The presence of oxygen in the environment presents both advantages and threat to all forms of life. The use of oxygen as a final electron acceptor provides more energy than that afforded by anaerobic fermentation. Oxygen is also useful in many biosynthetic reactions.
