Overproduction of peroxide-scavenging enzymes in Escherichia coli suppresses spontaneous mutagenesis and sensitivity to redox-cycling agents in oxyR-mutants.
Mutations that suppressed the H2O2 sensitivity of Escherichia coli oxyR- strains caused elevated levels of one three enzymes that destroy organic and hydrogen peroxides: catalase-hydroperoxidase I (the katG gene product), catalase-hydroperoxidase II (controlled by katEF) or alkyl hydroperoxide reduc...
