pAndersonJ23115:RBS:tetR-terminator



Usage and Biology

This parts consists of AndersonJ23115 promoter BBa_K3505012 , TetR BBa_K3505005 and Double Terminator BBa_K3505017. By this way ,as AndersonJ23115 is a strong constitutive promoter, TetR is constitutively expressed. TetR binds to tetracycline response element and inhibits the expression of a desirable transcription unit (Gossen and Bujard, 1993).

Design Notes

The coding sequence was domesticated . We removed BsmBI ,BsaI , BtgZI, BpiI sites in order to be compatible with GoldenBraid and MoClo. The sequence is cloned in alpha1R vector BBa_K3505008 and has overhangs compatible for GoldenBraid cloning.
