UvrY DNA-binding transcriptional activator

Synonyms: UvrY-phosphorylated, UvrY
The protein belongs to the LuxR/UhpA family. This regulator participates in controlling several genes involved in the DNA repair system and carbon metabolism. UvrY has been shown to be the cognate response regulator for the BarA sensor protein. UvrY requires the presence of IHF for binding to csrB but not csrC [1] The genes regulated by this two-component sytem have yet to be identified. The signal the system responds to is also not known, but may be associated with hydrogen peroxide-mediated stress [4].
