The Fenton or Fenton-type reaction between aqueous ferrous ion and hydrogen peroxide
generates a highly oxidizing species, most often formulated as hydroxyl radical or ferryl …

A reductive paradigm has emerged in recent years for detoxification of superoxide and other
redox active diatomic molecules in air-sensitive bacteria and archaea. Adventitiously …

Some sulfate-reducing and microaerophilic bacteria rely on the enzyme superoxide
reductase (SOR) to eliminate the toxic superoxide anion radical (O 2·−). SOR catalyses the …

Publisher Summary This chapter emphasizes that treponema pallidum, subspecies pallidum
can occur in late stages of neurosyphilis cause dementia, cortical atrophy, and amyloid …

Thermotoga maritima, an anaerobic hyperthermophilic bacterium, was found able to grow in
the presence of low concentrations of oxygen of up to 0.5%(v/v). Differential proteomics and …

Superoxide reductase (SOR) catalyzes the reduction of O2•-to H2O2. Its active site consists
of a non-heme Fe2+ center in an unusual square-pyramidal [His4 Cys] coordination. Like …

Superoxide reductases (SORs) are superoxide (O2−)-detoxifying enzymes that catalyse the
reduction of O2− into hydrogen peroxide. Three different classes of SOR have been reported …

Background Superoxide reductases (SOR) catalyse the reduction of superoxide anions to
hydrogen peroxide and are involved in the oxidative stress defences of anaerobic and …

Peroxidase‐like layered double hydroxide (LDH) nanoflakes were synthesized directly and
facilely by a one‐pot chemical method, hydrothermal treatment. The as‐prepared LDHs …

The superoxide radical O2· ̅ is a toxic by-product of oxygen metabolism. Two O2· ̅
detoxifying enzymes have been described so far, superoxide dismutase and superoxide …
