ArcA binds to the regulatory region of the ompD gene ompD transcription assessments suggest the existence of a regulatory mechanism .
Although unphosphorylated ArcA was also able to bind the ompD promoter , the electro-phoretic mobility pattern was different from that .
ompD downregulation is lost in arcA mutants To investigate ArcA-mediated regulation of ompD expression upon 3 xFLAG genetic background .
ompD downregulation is lost in arcA mutants To investigate ArcA-mediated regulation of ompD expression upon hydrogen-peroxide exposure , ΔarcA strains were constructed in wild type and OmpD .
negative regulation of ompD expression as previously observed in wild type cell _ supporting the idea that ArcA is directly involved in downregulating ompD expressio
Although results from gel shift assays suggest that ArcA-mediated control of ompD expression under oxidative-stress is dependent on ArcA phosphorylation , additional evidence is required to elucidate the signaling pathway .
