Iron and manganese superoxide dismutases are phylogenetically closely related. They are compared by in silico analysis with regard to their metal specificity and their three-dimensional structure. Special attention is given to the structure and properties of superoxide dismutases from archaeal prokaryotes. The mechanism and the extreme thermostability of superoxide dismutase from Sulfolobus aci...

BACKGROUND AND PURPOSE Free radicals including superoxide are responsible for postlesional cytotoxicity. In contrast to the constitutive CuZn-superoxide dismutases (SODs), manganese-superoxide dismutase (Mn-SOD) is inducible and has the potential to protect neurons by its superoxide dismutating activity. Therefore, we studied the presence and the regional changes in Mn-SOD within the brain afte...

background: superoxide radicals are produced during oxidative metabolic processes, and removed by superoxide dismutase (sod) enzymes. controversial results have been reported regarding the tissue and plasma concentration of sod in patients with breast cancer. methods: venous blood was obtained from study participants and activity of sod enzyme was determined in 100 women. comparison was made be...
