While H-NS usually acts as a negative regulator of gene expression , hlyE is not the only example of a CRP-regulated gene whose expression is positively regulated by H-NS ; for example , expression of both the malT and csiD genes in E. coli is stimulated by H-NS ( 8 , 14 ) .
Thus , we concluded that CRP all contribute towards the regulation of hlyE expression .
In summary , the data suggest that CRP are positive regulators of hlyE expression in liquid culture in response to glucose-starvation , respectively .
In summary , the data suggest that CRP are positive regulators of hlyE expression in liquid culture in response to oxygen , respectively .
This reciprocity of transcriptional efficiency provides a mechanism for the moderate upregulation of hlyE expression in response to two distinct environmental signals rather than , for the much larger degree of upregulation when CRP act synergistically by binding at different sites within the ansB promoter .

Nevertheless , genetic experiments showed that CRP participates in the negative regulation of hlyE in S. Typhi since crp deletion led to increased β-galactosidase activit .
Altogether , these results suggest that CRP are able to repress the rpoS expression by direct binding , thereby regulating hlyE expression in S. Typhi .
