In the previous report , H-NS acted as a strong repressor of hlyE expression , whereas here H-NS appears to have a positive effect on hlyE expression in the absence of glucose but an negative effect on hlyE expression in the presence of glucose .
In the previous report , H-NS acted as a strong repressor of hlyE expression , whereas here H-NS appears to have a positive effect on hlyE expression in the absence of glucose but an attenuated effect on hlyE expression in the presence of glucose .
This suggests that , in general , H-NS inhibits FNR-driven hlyE expression .
In hlyE are transcriptionally repressed by the nucleoid-associated protein H-NS .
