Description
Technical Field
The invention relates to the technical field of biology, in particular to recombinant saccharomyces cerevisiae for producing α -lupinene, 8-hydroxy- α -lupinene and zingiberone and a construction method thereof.
Background
The biosynthesis pathway of zingerone is now clear, and similar to the biosynthesis of other sesquiterpene compounds, farnesyl pyrophosphate (FPP) is derived from mevalonate pathway (MVA). FPP is catalyzed by α -lupinene synthase ZSS1 to synthesize α -lupinene, α -lupinene, also known as α -caryophyllene or humulene, and is a natural monocyclic sesquiterpene compound, which is found in essential oils of hops of the Humulaceae family, so it is also known as humulene, α -lupinene in beer has anti-cold effect, α -lupinene has anti-inflammatory effect, and is likely to be an effective drug for treating inflammatory diseases.
The accumulation of terpenoids in plants is less, the extraction and purification by using plant raw materials are low in yield and purity, and a large amount of plant raw materials are needed; the synthesis of terpenes by chemical synthesis is widely used, but for terpenoids with complex structures, it is still difficult and costly. At present, the zingerone is only found in the Zingiberaceae plants, although the biosynthesis pathway is already explained, the synthesis regulation mechanism of the zingerone in plant hosts is not reported, and the improvement of the production of the zingerone by modifying the original hosts by a metabolic engineering means is still difficult.
