<partinfo>BBa_K544003 short</partinfo>A transcriptional regulator TetR (BBa_C0040) is driven by constitutive promoter family members (BBa-J23103, BBa-J23109, BBa-J23116, and BBa-J23106), which can be used to tune the expression level of constitutively expressed TetR.

The tetR-HNS2-90 protein fuses the polymerization demain of histone-like nucleoid-structuring (H-NS) protein to tetR. Thus, in E.coli, when TetR-HNS2-90 binds the TetR-specific DNA motif, it will recruit native H-NS to bind to adjacent DNA, which may lead to local gene silencing. This fusion protein is driven by constitutive promoter family members (BBa-J23103, BBa-J23109, BBa-J23116, and BBa-J23106). Experimental data indicates that TetR-HNS2-90 is more effective than TetR on transcription repression.

Tetracycline Repressor with Consitutive Promoter BBa_J23116A transcriptional regulator TetR (BBa_C0040) is driven by constitutive promoter family members (BBa-J23103, BBa-J23109, BBa-J23116, and BBa-J23106), which can be used to tune the expression level of constitutively expressed TetR.
