Usage and Biology

This parts consists of AndersonJ23115:TetR:Double Terminator BBa_K3505033 and AndersonJ23115:TetO:RBS-LacI-Double Terminator BBa_K3505034. By this way ,as AndersonJ23115 is a strong constitutive promoter, TetR is constitutively expressed and binds to tet operator, inhibits the expression of a LacI.

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 omega1 vector BBa_K3505010 and has overhangs compatible for Golden Braid cloning.
