Part:BBa_K3505014

AndersonJ23115:TetO:RBS GB compatible with A1-B2

Constitutive Anderson BBa_J23115with Tet Operator and RBS BBa_B0034

Usage and Biology

This part is a constitutive promoter from Andesron family , J23115 , having downstream with a Τet Operator and RBS. The activity of this part is regulated by TetR BBa_K3505003. TetR binds to TRE -tetracycline response element, and inhibits the expression of the desirable transcription unit. This part can be used in a Tet-off system, expression of Tet-regulated genes can be inhibited by tetracycline and its chemical derivatives , such as anhydrotetracycline aTc-a strong chemical repressor , that binds to TRE and the desirable transcription unit is blocked.

Design Notes

The sequence was domesticated . We removed BsmBI ,BsaI , BtgZI, BpiI sites in order to be compatible with GoldenBraid and MoClo. The sequence is cloned in pUPD2 BBa_K3505007 and has overhangs compatible for Golden Braid cloning. This has position A1-B3.
