FEMS microbiology letters - 1 Sept 1995
Schellhorn H E
Abstract excerpt
As part of its adaptive response to oxidative stress, Escherichia coli produces two inducible hydroperoxidases called HPI and HPII. Upon exposure to sublethal levels of hydrogen peroxide, HPI expression is induced at the transcriptional level by OxyR, a member of the LysR family of autoregulators...
