Ptet promoter

-

Biology:

    This part is inducible promoter Ptet which is induced by tetracycline. This is the basic principle of Tet induced expression system, it is to regulate the conformation of proteins by inducer such as Tet, thus controlling the expression of target proteins. When there is no tetracycline, TetR will bind to TetO to block downstream expression of resistant genes. When tetracycline is added, it will bind to TetR and change its conformation, then TetR is separated from TetO, thereby relieving the inhibition of resistance genes.
