Simvastatin is one of the important prescription drugs for hypercholesterolemia. Monacolin J is a key intermediate during simvastatin synthesis, and also an intermediate of lovastatin biosynthesis. In this work, we construct a monacolin J producing strain via RNA interference to achieve one-step fermentation to obtain simvastatin. The lov F gene silencing plasmid p MHJ137 was constructed and transformed into Aspergillus terreus by Agrobacterium tumefaciens mediated transformation method. Precursor DMB-S-MMP...
