Applications of BBa_K1088004

The genes dxs and ispG were placed on the backbone of low-copy plasmid pBBR1MCS-2, and the promoter was medium strength lac promoters, to construct plasmid pBBR1MCS-2-dxs-ispG (pMEP-DG).

Genes ispH, idi, and ispA were placed on the backbone of high-copy plasmid pETDuet-1, and the promoter was strong promoter T7 to construct plasmid pETDuet-1-1T7-IspH-Idi-IspA-Yss (pET-HIAY).

When Dxs and IspG were overexpressed, the squalene yield increased by 4.3 times. We speculated that the overexpressed gene ispG was constructed on low-copy plasmids and was controlled by promoters of medium strength, so it didn’t produce large amounts of harmful intermediate HMBPP. And overexpressing Dxs promoted the metabolic flow, increasing the squalene yield.
