Általános leírás
Superoxide dismutases are a group of low molecular weight metalloproteins present in all aerobic cells of plants, animals and micro-organisms. They provide protection against damaging reactions with the superoxide radical anion (O2-) by catalyzing its disproportionation into oxygen and hydrogen peroxide. The direct electron transfer of superoxide dismutases can be efficiently promoted by a self-assembled monolayer of 3-mercaptopropionic acid confined on a gold electrode.
Alkalmazás
Superoxide dismutase from Escherichia coli has been used in a study to determine that anion binding properties of reduced and oxidized iron-containing superoxide dismutase reveal no requirement for tyrosine 34. Superoxide dismutase from Escherichia coli has also been used in a study to demonstrate that molecular dynamics simulation and limited proteolysis are complementary and specific tools to identify flexible sites in proteins.
Biokémiai/fiziológiai hatások
Catalyzes the dismutation of superoxide radicals to hydrogen peroxide and molecular oxygen. Plays a critical role in the defense of cells against the toxic effects of oxygen radicals. Competes with nitric oxide (NO) for superoxide anion (which reacts with NO to form peroxynitrite), thereby SOD promotes the activity of NO. SOD has also been shown to suppress apoptosis in cultured rat ovarian follicles, neural cell lines, and transgenic mice.

Immunization with Mycobacterium tuberculosis heat shock protein (hsp) 60 has been shown to protect rats from experimental arthritis. Previously, the protection-inducing capacity was shown to reside in the evolutionary conserved parts of the molecule. Now we have studied the nature

Inhibition of bacterial cell wall synthesis by antibiotics such as β-lactams is thought to cause explosive lysis through loss of cell wall integrity. However, recent studies on a wide range of bacteria have suggested that these antibiotics also perturb central
