LITERATURE
synthesis
introduction of a gene cluster encoding six enzymes of the mevalonate pathway into Escherichia coli and coexpression with ZSS2. When supplemented with mevalonate, the engineered Escherichia coli produces a similar sesquiterpene profile to that produced in the in vitro enzyme assay, and the yield of beta-eudesmol reaches 100 mg/l
