Why do bacteria use so many enzymes to scavenge hydrogen peroxide?

Archives of biochemistry and biophysics - 15 Sept 2012

Mishra Surabhi, Imlay James

Abstract excerpt

Hydrogen peroxide (H(2)O(2)) is continuously formed by the autoxidation of redox enzymes in aerobic cells, and it also enters from the environment, where it can be generated both by chemical processes and by the deliberate actions of competing organisms. Because H(2)O(2) is acutely toxic, bacteria elaborate scavenging enzymes to keep its intracellular concentration at nanomolar levels. Mutants that lack such...
