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.
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.
