The double hns hha-mutant showed the highest b-galactosidase activities at low-temperature , indicating that Hha enhances H-NS-mediated hilA silen-cing .
The double hns hha-mutant showed the highest b-galactosidase activities at both low-osmolarity , indicating that Hha enhances H-NS-mediated hilA silen-cing .
The Hha protein enhances the silencing effect of H-NS on hilA .
