Design Notes

The purpose of this part is to overexpress ilvB/N in E. coli.

The ilvB/N genes were isolated from E. coli MG1655 through PCR, digested with NcoI and EcoRI, and cloned into the pETDUET-1 vector downstream a T7 promoter and RBS. This part is not strictly necessary for production of acetoin in E. coli but improves the production thereof.
