Transcription of katN is RpoS and growth phase dependent Salmonella strains carrying the Tn5B21 inserts G57 and I28 were initially selected because they contain RpoSregulated lacZ gene fusions ( Ibanez-Ruiz et al. , 2000 ) .
Thirty-eight unique mutants _ carrying transcriptional lacZ gene fusions positively regulated by RpoS
Vijayakumar , S.R. , Kirchhof , M.G. , Patten , C.L. , and Schellhorn , H.E. ( 2004 ) RpoS-regulated genes of Escherichia coli identified by random lacZ fusion mutagenesis .
To further examine the SraL regulation by RpoS , we analyzed sraL promoter response in a transcriptional-fusion to lacZ reporter gene in both rpoS mutant genetic backgrounds .
To further examine the SraL regulation by RpoS , we analyzed sraL promoter response in a transcriptional-fusion to lacZ reporter gene in both wild-type .
