Thus , the LeuO regulators positively regulate ompS2 .
The experiments described above indicated that both the LeuO were involved in the positive regulation of ompS2 expression .
LeuO participates in the regulation of ompS2 .
LeuO bound to the 5 upstream regulatory region of ompS2 in two .
IMSSTN103 where the transposon insertion allowed us to identify LeuO as a positive regulator of ompS2
the original S. Typhi Tn-10 insertion mutant where the transposon insertion allowed us to identify LeuO as a positive regulator of ompS2

the original S. Typhi Tn-10 insertion mutant where the transposon insertion allowed us to identify LeuO as a positive regulator of ompS2
The observation that both ompS2 were regulated by LeuO at different levels of induction opens the possibility that there is a regulon in S. enterica .
Bacterial strains IMSS-II ( Salmonella serovar Typhi IMSS-1 harboring plasmid pFMTrc12 ) and IMSS-III ( Salmonella serovar Typhi IMSS-1 harboring plasmid pFMTrcleuO-50 ) were independently transformed with fusions of each of the LeuO-regulated genes ( pKK232-9 [ STY3070 ] , pKK232-9 [ assT ] , pKK232-9 [ ompS1 ] , pKK232-9 [ ompS2 ] , pKK232-9 [ tpx ] , pKK232-9 [ ompX ] , and pKK232-9 [ STY1978 ] ) to generate individual strains containing the LeuO regulator , as well as the promoter region of the LeuO-dependent gene .
A previous report showed that LeuO bound to the promoter region of ompS2 at 93 to 109 to the transcription start site .
ompS2 is positively regulated by the LeuO regulator by derepressing the HN-S action
