Tet O operator library member

These parts have been extracted from the TeT Operator Library.

K079036:Tet O is the Wild Type operator sequence regulating Tetracycline resistance genes. The natural sequence exhibit a tigth repression given by an high Tet R bindig affinity K079037:TetO-4C is a medium affinity operator obtained through a T-C mutation in the fourth nucleotide on both side of the symmetric consensus sequence. Disrupting this interaction the repression efficiency is about 12 time lower than the Wt K079038: TetO-wt/4C5G is a double mutant that heavily compromises the interaction of TetR with the right half of the binding sequence. The resulting repression is quite weak, more than 40 times less stringent than in TetO
