The manganese and iron superoxide dismutases protect Escherichia coli from heavy metal toxicity.

Research in microbiology - 1 Dec 2001

Geslin C, Llanos J, Prieur D, Jeanthon C

Abstract excerpt

Superoxide dismutases (SODs) are vital components that defend against oxidative stress through decomposition of superoxide radical. Escherichia coli contains two highly homologous SODs, a manganese- and an iron-containing enzyme (Mn-SOD and Fe-SOD, respectively). In contrast, a single Mn-SOD is present in Bacillus subtilis. In E. coli, the absence of SODs was found to be associated with an increased sensitivity...
