Negative Regulation of DNA Repair Gene (ung) Expression by the CpxR/CpxA Two-Component System in Escherichia coli K-12 and Induction of Mutations by Increased Expression of CpxR
In Escherichia coli K-12 overexpressing CpxR, transcription of the ung gene for uracil-DNA glycosylase was repressed, ultimately leading to the induction of mutation. Gel shift, DNase I footprinting, and in vitro transcription assays all indicated negative regulation of ung transcription by phosphor...
