Description
This part is a composite structure which contains a promoter, RBS side and and a tetracycline repressor from transposon Tn10. It is transcribed in the opposite direction for the coding sequence of the repressor AraC. Through the binding to L+arabinose, the conformation of AraC changes.This causes the protein to diffuses from the DNA thereby inducing transcription. Through the RBS, the definition of the RBS efficiency could be observed.As the second part we added Terminator+Tetr Promoter+T4 Endolysin.
For this part an artifical Terminator is used (generally added to another parts). The promoter is a TetR repressible promoter.It is sequenced for pTet inverting regulator. Promoter is constitutively ON and repressed by TetR. TetR repression is inhibited by the addition of tetracycline or its analog part
Notes
L(+) - Arabinose is in sugar form and harmless The designed promoter has low background activity, so the membrane proteins will not damage the cells before induction.Bidirectional, with the reverse estimated to be more effective than the forward. Has a polyA tail of 9 residues. High expression of lysozyme only is toxic to bacteria. BBa_R0040 (TetR repressible promoter) is based on a cI promoter. It has been modified to include two TetR binding sites. Constructed by DNA synthesis.
