Biosynthesis of (R)-(+)-perillyl alcohol by Escherichia coli expressing neryl pyrophosphate synthase.

ABSTRACT: (R)-(+)-perillyl alcohol is widely used in agricultural and anticarcinogenic fields. Microbial production of (R)-(+)-perillyl alcohol was investigated in this study. We optimized biosynthesis of (R)-(+)-perillyl alcohol in Escherichia coli by using neryl pyrophosphate synthase and NADPH regeneration. Engineering neryl pyrophosphate (NPP)-supplied pathway resulted in a 4-fold improvement of (R)-(+)-perillyl alcohol titer. Subsequently, combined engineering of p-cymene monooxygenase (CymA) expression and module for NADPH regeneration exhibited a 15.4-fold increase of titer over the initial strain S02. Finally, 453 mg/L (R)-(+)-perillyl alcohol was achieved in fed-batch fermentation, which is the highest (R)-(+)-perillyl alcohol titer in
