In our study, we aim to achieve limonene and linalool synthesis in E.coli DH5 . According to 2018 team GreatBay_China’s experience, no target product was detected using gas chromatography when carrying out shake-flask fermentation with this strain induced by 25uM IPTG for 24 hours due to the lack of endogenous MVA pathways wherein GPP is produced. Thus we decided to co-express an MVA pathway. 2018 team GreatBay_China generously gave us one plasmid pJBEI6409, which contains a MVA pathway in addition to an GPPs-LS operon. We reconstructed this plasmid and get a plasmid only contains a MVA pathway. | In our study, we aim to achieve limonene and linalool synthesis in E.coli DH5 .

(4S)-limonene synthase
The limonene synthase (LS) sequence used throughout our project which converts GPP to limonene is an E. coli codon-optimized version of a truncated sequence from M. spicata previously described(Hyatt et al., 2007).

Background
In our study, we aim to achieve limonene and linalool synthesis in E.coli DH5 . According to 2018 team GreatBay_China’s experience, no target product was detected using gas chromatography when carrying out shake-flask fermentation with this strain induced by 25uM IPTG for 24 hours due to the lack of endogenous MVA pathways wherein GPP is produced. Thus we decided to co-express an MVA pathway. 2018 team GreatBay_China generously gave us one plasmid pJBEI6409, which contains a MVA pathway in addition to an GPPs-LS operon. We reconstructed this plasmid and get a plasmid only contains a MVA pathway.
