Background:

Anhydrotetracycline (hydrochloride) (ATC) is a powerful effector for the tetracycline repressor (TetR) and reverse tetracycline repressor (revTetR) systems [1].

Tetracycline repressor (TetR) is an effector-regulated DNA-binding protein that binds tightly to its palindromic tetO operator DNA in the absence of effector, thereby blocking the transcription of any downstream genes. Binding of tetracycline (TC) or anhydrote-tracycline (ATC) to TetR causes the repressor to dissociate from the DNA and gene transcription can occur. Contrary to TetR, reverse tetracycline repressor (revTetR) mutant binds tetO only in the presence of ATC [2][3].

Anhydrotetracycline (hydrochloride) is a powerful effector for TetR and revTetR systems. Anhydrotetracycline (ATC) bound TetR with a 500-fold higher affinity and represented the most efficient inducer [2]. ATC bound the Tet repressor 35-fold more potent than Tet [4]. However, ATC acted as a corepressor in revTetR variant. In β-galactosidase (β-gal) assays, TetR inhibitedβ-gal expression to nearly 1%, while
