TetR repressible promoter

Sequence for pTet inverting regulator. Promoter is constitutively ON and repressed by TetR. TetR repression is inhibited by the addition of tetracycline or its analog, aTc.

Usage and Biology

Medium strength promoter. [jb, 5/24/04]

From the reference article:
"In contrast to tetracycline, anhydrotetracycline is a particularly useful inducer. It binds Tet R with an ~35-fold higher binding constant and thus allows to operate at very low concentrations. At the same time, its antibiotic activity is ~100-fold lower and concentrations of <50 ng/ml as required for the full induction of P LtetO-1 have no effect on the growth of E.coli."
