regulation using the cell's response to heterologous pathway expression and metabolite (FPP here) toxicity

The bottom section of the figure depicts the SynBERC researchers’ approach: regulation using the cell's response to heterologous pathway expression and metabolite (FPP here) toxicity. The top section of the figure shows regulation using more typical inducible promoters.(Credit: SynBERC)
