Description
This promoter is a modified version of the Mnt promoter that is also responsive to TetR. The promoter should be repressed by Mnt repressor. It should also be repressed by TetR, and in the absence of Mnt repressor, should be induced by aTc.
Notes
Mnt repressor binds as a tetramer to two half-operator sites. Introduction of TetR binding sites between the Mnt promoter -10 sequence and the start site for transcription should allow for repression by TetR. Accordingly, the hybrid promoter was designed by 1) Remove all bases of mnt promoter 3??? to -10: gagtcgtattaattt will be replaced by tccctatcagtgata, and 2) truncate the second half of ptet -10 and mutate -35 so that it function to bind tetR (replace ttgaca with actgta), but is not a promoter, and 3) place the tetR1 and tetR2 binding sites 3??? to truncated mnt -10 sequence.

This part comes from the Mnt promoter and the TetR promoter
