B. subtilis dxs (lac promoter with lac inhibitor: IPTG inducible)
This part consist of the dxs gene derived from B. subtilis under the control of the lac promoter and has a strong RBS.
To repress expression from the lac promoter, the lacI:LVA gene (under a constitutive promoter, with a strong RBS and a efficient terminator) was placed counter-clockwise to the dxs gene. The repression can be relieved with addition of IPTG, which binds and inhibits the function of LacI:LVA.
The levels of expression was meassured with a similar Brick with linker-GFP fused to Dxs (BBa_1088009) in E. coli K-12 MG1655 using fluorescence activated cell sorting (FACS). The experiment proved that the reporter fusion wasn't expressed when the strain was grown without IPTG in the media, and that the reporter fusion was expressed after addition of IPTG. See experience for more details.
