Expression of STY3070 was induced in an hns mutant , consistent with the notion that H-NS represses these genes ; transcriptional activity was lower for tpx in an hns background , suggesting that this global regulatory protein has a positive effect .
Expression of assT was induced in an hns mutant , consistent with the notion that H-NS represses these genes ; transcriptional activity was lower for tpx in an hns background , suggesting that this global regulatory protein has a positive effect .
Expression of ompS1 was induced in an hns mutant , consistent with the notion that H-NS represses these genes ; transcriptional activity was lower for tpx in an hns background , suggesting that this global regulatory protein has a positive effect .
Interestingly , the results indicate that H-NS is a positive regulator of tpx ; one possibility is that in an hns mutant the levels of LeuO increase since leuO is repressed by H-NS .
global microarray analysis indicated that H-NS represses tpx expression .
