“…Also, we established that feoA is encoded in an operon that emerged in the common ancestor of most, but not all, helicobacters, and this resulted in feoA transcription being controlled by two independent promoters. …”

“…Loss of Dam led to modulation of genome-wide gene expression, and several Dam-target sites including the promoter region of the trmD operon (rpsP, rimM, trmD, and rplS) were identified through our methylome and transcriptome analyses. …”

“…As an extension of our previous work, where the expression of the mexAB-oprM operon is directly activated by CpxR in P. aeruginosa, in this study, we showed that the expression of the mexA promoter was increased in the above cpxS mutant strains in a cpxR-dependent manner, and mexA is prerequisite for the reduced antibiotic susceptibility. …”

“…Sub-inhibitory concentrations of DNA created a cation-limited environment that resulted in induction of the PhoPQ- and PmrAB-regulated cationic antimicrobial peptide resistance operon PA3552–PA3559 in P. aeruginosa. Furthermore, DNA-induced expression of this operon resulted in up to 2560-fold increased resistance to cationic antimicrobial peptides and 640-fold increased resistance to aminoglycosides, but had no effect on β-lactam and fluoroquinolone resistance. …”

“…We constructed a transposon (transposon assisted gene insertion technology, or TAGIT) that allows the random insertion of gfp (or other genes) into chromosomal loci without disrupting operon structure or regulation. TAGIT is a modified Tn5 transposon that uses Kan(R) to select for insertions on the chromosome or plasmid, β-galactosidase to identify in-frame gene fusions, and Cre recombinase to excise the kan and lacZ genes in vivo. …”

RecBC is the only recombination protein required for cell viability under these conditions of increased replication-transcription collisions. …”
