Some Properties of Cu, Zn-Superoxide Dismutase from Sheep Erythrocyte
نویسندگان
چکیده
The activity variations and stability properties of sheep erythrocyte Cu, Zn-SOD were investigated under the optimized activity assay conditions by observing inhibition change at the autoxidation rate of 6-OHDA. The optimum pH and temperature of sheep erythrocyte Cu, Zn-SOD were found to be 9.4 and 30◦C respectively. The enzyme showed high pHand thermal-stability properties around neutral pH and up to 37◦C after 2.5 h incubation. Variations in the inhibition percentage of autoxidation were investigated in 0.2-0.9 mM range of 6-OHDA. The same procedures were repeated by adding catalase also.

Human Erythrocyte Superoxide Dismutase Encapsulated in Positively Charged Liposomes
Superoxide dismutase (SOD) is an important antioxidant that protects many types of cells from the free radical damage. One of the possible ways for the use of SOD is its incorporation in liposomes. The aim of this study was to investigate the effect of cationic phospholipids on the entrapment of human erythrocyte superoxide dismutase (Cu/Zn SOD) in liposomes. Also, in the present study, w...

Cu,Zn-superoxide dismutase (Cu,Zn-SOD) is a ubiquitous enzyme with an essential role in antioxidant defense. To better understand structural factors at the origin of the highly efficient superoxide dismutation mechanism, we analyzed the consequence of copper reduction on the electronic properties of the backbone and individual amino acids by using electrochemistry coupled to Fourier transform i...
متن کاملProduction and characterization of recombinant Aspergillus fumigatus Cu,Zn superoxide dismutase and its recognition by immune human sera.
The Cu,Zn superoxide dismutase (SOD) of Aspergillus fumigatus has previously been purified and shown to be immunoreactive to the sera of patients with aspergillosis; however, the purification of large quantities of the enzyme for expanded immunological analysis is both difficult and time-consuming. Accordingly, a lambdaEMBL3 A. fumigatus genomic library was screened with degenerate oligonucleot...
متن کاملAge- and sex-dependent effects of long-term zinc supplementation on essential trace element status and lipid metabolism in European subjects: the Zenith Study.
Given the key role of Zn in many physiological functions, optimal Zn status could be a predictive parameter of successful ageing. However, the benefit of Zn supplementation is still a matter of debate since Zn supplementation has been reported to be associated with the alteration of Cu status and lipid metabolism. As part of the Zenith Project, the present study aimed to investigate, in free-li...
متن کاملParticipation of metallothionein and superoxide dismutase in the blood of smoking smelters.
OBJECTIVES Metallothionein (MT) and two forms of superoxide dismutase (SOD), which are dependent on zinc and copper ions, are involved in defense against the same superoxide anion radicals and are present in extra- and intracellular compartments. The aim of our study was to investigate MT concentration and Cu/Zn SOD activity in the plasma and erythrocyte lysate of the non-smoking and smoking sm...
