pMnt/Lac is constitutively on but is repressed by the LacI protein. The promoter is also repressed by the Mnt protein. The addition of IPTG should repress the LacI repressor and glow in the absence of the Mnt protein.
To Test repression of promoter
Some promoter→RBS+LacI+t+t+pLac/Mnt→RBS+GFP does not glow
I13453 → B0034 +LacI+TT+ K091104→E0240
Some promoter→RBS+Mnt+t+t+pLac/Mnt→GFP does not glow
I13453 → B0034 +Mnt+TT+ K091104→E0240
Some promoter→RBS+LacI+RBS+Mnt+t+t+pLac/Mnt→GFP does not glow
I13453 → B0034 +LacI+RBS+Mnt+TT+ K091104→E0240
To Test the promoter and addition of IPTG
add IPTG
Some promoter→IPTG+RBS+LacI+t+t+pLac/Mnt→GFP glows
I13453 → IPTG+B0034+LacI+TT+K091104→E0240
Some promoter→IPTG+RBS+LacI+Mnt+t+t+pLac/Mnt→GFP glows
I13453 →IPTG+ B0034 +LacI+RBS+Mnt+TT+ K091104→E0240
| LacI | Mnt | IPTG + GFP | IPTG - GFP |
|---|---|---|---|
| 0 | 0 | 1 | 1 |
| 0 | 1 | 0 | 0 |
| 1 | 0 | 1 | 0 |
| 1 | 1 | 0 | 0 |
Steps to Build Hybrid Promoter
6/30/08
Perform a Ligation of Mnt/Lac (K091104) with E0240 (RBS + GFP)
Transform ligation over night
7/1/08
Clones were picked and set over night in LB + AMP
