B. subtilis dxs (lac promoter without lac inhibitor)

This part contains the dxs gene derived from B. subtilis (BBa_K1088000) controlled by the lac promoter and has a strong RBS. The part was build to increase the flow through the MEP (methylerythritol phosphate) pathway, and to test whether Dxs derived from E. coli or B. subtilis increased the flow through the MEP pathway the most in E. coli.

The lac promoter is repressed by the LacI protein, and repression can be relived through allosteric binding of IPTG to the repressor.

Fluorescence activated cell sorting (FACS) was used to assay the protein expression profile of a similar part (Ba_K1088008) with linker-GFP attached C-terminal to Dxs. Experiments proved that this part is constitutively active when LacI isn't overexpressed in the cell. See Ba_K1088008 for more details.
