How Escherichia coli tolerates profuse hydrogen peroxide formation by a catabolic pathway.

Journal of bacteriology - 1 Oct 2013

Ravindra Kumar Sripriya, Imlay James A

Abstract excerpt

When Escherichia coli grows on conventional substrates, it continuously generates 10 to 15 μM/s intracellular H2O2 through the accidental autoxidation of redox enzymes. Dosimetric analyses indicate that scavenging enzymes barely keep this H2O2 below toxic levels. Therefore, it seemed potentially problematic that E. coli can synthesize a catabolic phenylethylamine oxidase that stoichiometrically generates H2O2....
