The sodA gene from Erwinia chrysanthemi strain 3937 was cloned by functional complementation of an Escherichia coli sodA sodB mutant and sequenced. We identified a 639-bp open reading frame, which encodes a protein that is 85% identical to the E. col

The superoxide radical O 2 ·̅ is a toxic by-product of oxygen metabolism. Two O 2 ·̅ detoxifying enzymes have been described so far, superoxide dismutase and superoxide reductase (SOR), both forming H 2 O 2 as a reaction product. Recently, the SO

Recombinant iron-containing superoxide dismutase (Fe-SOD) from Plasmodium falciparum was produced in a SOD-deficient strain of Escherichia coli, purified and characterised. The enzyme is a dimer, which contains 1.7 Fe equivalents and is sensitive to

Reactive oxygen species are produced as an early event in plant defense response against avirulent pathogens. We show here that alfalfa responds to infection with Sinorhizobium meliloti by production of superoxide and hydrogen peroxide. This similari

Two global regulators repress the anaerobic expression of MnSOD in Escherichia coli: Fur (ferric uptake regulation) and Arc (aerobic respiration control)

Autor: Brigitte Tardat, Danièle Touati

Publikováno v: Molecular Microbiology. 5:455-465

The expression of sodA, the Escherichia coli gene encoding manganese superoxide dismutase (MnSOD) is induced by aerobiosis and superoxide generators such as paraquat. Analysis of variants expressing sodA in the absence of oxygen has revealed that mut
