By expressing the tetR:H-NS fusion proteins, the tetR part of the proteins wound recognize and specifically bind to the tetR binding region (tetO2). There are two tet-R binding sites as tet-R form a dimer as in the tet repressor- operator system. As the fusion proteins bound to tet-O, it is expected that the H-NS part of the fusion protein would attract and oligomerize with other native H-NS proteins inside the cell. With the oligomerization of the fusion proteins and native H-NS, the DNA covered by the oligomers is expected to trap the RNA polymerase during transcription, thus gene (GFP) repression is achieved.

Experience:

We have entered the confirmation data for the characterization of the selected constitutive promoters we have used. Of the 4 promoters we have used in the project, our team considered that J23109 or J23116 are more suitable promoters in creating the super silencer repression system.
