(+)-Valencene is a bioactive sesquiterpene that can be used for flavoring and fragrances, and microbial production provides an alternative sustainable access. However, the complexity of cellular metabolism makes it challenging for its high-level production. Here, we report the global rewiring cellular metabolism for de novo production of (+)-valencene in yeast Saccharomyces cerevisiae by engineering central metabolism, mevalonate pathway, and sesquiterpenoid synthase. In particular, we show that metabolic transformation can help accelerate the strain construction process and multiple copy expression of sesquiterpenoid synthase is essential for boosting the metabolic flux for product synthesis with enhanced supply of precursors. The engineered strain produced 1.2 g/L (+)-valencene under fed-batch fermentation in shake flasks, which was increased by 549-fold and demonstrated great potential of the yeast cell factory for (+)-valencene production.
