RegulonDB RegulonDB 10.8: Operon Form

ppdAB-ygdB-ppdC-recC operon and associated TUs in Escherichia coli K-12 genome

Name: ppdAB-ygdB-ppdC-recC
This page displays every known transcription unit of this operon and their known regulation.

Transcription unit       
Name: recC
Gene(s): recC   Genome Browser M3D Gene expression COLOMBOS
Note(s): There is a region of dyad symmetry upstream of recC, and this may be a region to control the gene expression.
Based on the bacteriostatic antibiotic-induced persister model, 37 and 9 genes were found to produce defects in rifampin- and tetracycline-induced persister formation, respectively. Only six mutants were found to overlap in both treatment-induced persister screens: recA, recC, ruvA, uvrD, fis, and acrB. Four of these mutants (recA, recC, ruvA, and uvrD) mapped to the DNA repair pathway, one mutant mapped to a global transcriptional regulator (fis), and one to a gene for an efflux protein (acrB) 29559967 Other genes that mapped to transporters, membrane biogenesis, LPS biosynthesis, flagellum biosynthesis, metabolism (folate and energy), and translation were more specific to rifampin-induced persisters 29559967

Note(s): Park et al showed in 2001 that transcription of ppdA is highly dependent on alternative factor σF Park K,2001. The transcription expression level was examined in a fliA-mutant background.
