Project description:LrhA, YafC, YdcI, and YhaJ are LysR-type transcription regulator in Escherichia coli K12. In this study the transcriptomes of E. coli K12 strain U4 (MG1655 derivative, rph+ flhDC(IS1) dgcJ∷IS1 crl::IS1 ilvG+ ΔlacZ; Yilmaz et al. 2020, J. Bacteriol 203 e00427-20, https://doi.org/10.1128/JB.00427-20) and isogenic ΔlrhA, ΔyafC, ΔydcI, and ΔyhaJ mutants grown in Tryptone medium to OD600 0.8 were determined. The data revealed few loci that may be specifically affected in one deletion mutant only, while most differentially expressed loci were up or down regulated in several of the mutants.
Project description:The aim of the study was to compare the transcriptome of E. coli K12 MG1655 cells lacking genes known to induce the Rtc RNA repair system, such as gor, mazF and srmB, to wild-type cells. In all cases, less than 1% of the genes were found to be differentially expressed.
