Depositor Comments

E. coli MEV15 is engineered to host sesquiterpenoid biosynthetic pathways. Sesquiterpenoid production is achieved by supplying the strain with plasmids encoding terpene cyclase and cytochrome P450s under the control of Marionette promoters (See https://www.addgene.org/kits/marionette-sensor-collection/ and 10.1038/s41589-018-0168-3). Sesquiterpenoid production can be induced by IPTG, vanillic aci, and other inducers controlling cytorhcome P450s. The strain has the upper MEV pathway from pMevT (addgene #17815) inserted into 4418413/4418414, the lower MEV pathway from pMBIS (addgene #17817) and E. coli ispA inserted into 4105665/4105664, the designed redox enzyme array inserteed into 3801913/3801912, and the Marionette cluster from sAJM.1506 (addgene #108254) inserted into 3753777/3752159 of E. coli BL21(DE3)'s genome. The nucleotide numbers are based on NCBI accession # NZ_CP053602. The redox enzyme array consists of fprD/fdxD from Streptomyces avermitilis, fpr/fldA from E. coli, fenr/fer1 from spinach chloroplasts, abd pdr/pdx (camA/camB) from Pseudomonas putida. The Marionette cluster was transferred using phage transduction, resulting in the replacement of nucleotides between 3745758/3839292 by those in the corresponding regions from sAJM.1506 (parent strain: E. coli MG1655), as evident by whole-genome sequencing.
