tetR-HNS (2-90) fusion protein (Consitutive Promoter: BBa-J23103)

Details

• Types: DnaRegion
• Roles: engineered_region; Composite
• Sequences: BBa_K544011_sequence (Version 1)

Description

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.

Notes

There is a internal Pst1 site at in H-NS coding region

Source

H-NS2-90 coding region was cloned from E. coli K-12 MG1655 genomic DNA.
