Part:BBa_K1475003

tetracyclin repressor from transposon Tn10

The coding region of the frequently used tetracycline repressor (TetR) Part:BBa_C0040 modified by removing the LVA rapid degradation tag, this will in theory serve to increase the protein half-life and in practice increase the concentration of the protein in the cell. This TetR is the tTA subtype which on binding to the p(TetR) promoter Part:BBa_R0040 blocks transcription. [http://openwetware.org/wiki/ATc ATc (anhydrotetracycline)] binds to the Tet repressor inhibiting its function and hereby releasing the repression on the Tet promoter.

Usage and Biology

In addition to ATc (anhydrotetracycline), dox (Doxycycline) can also be used as inducer. [2]
