Biosynthesis of plant-specific phenylpropanoids by construction of an artificial biosynthetic pathway in Escherichia coli

Biological synthesis of plant secondary metabolites has attracted increasing attention due to their proven or assumed beneficial properties and health-promoting effects. Phenylpropanoids are the precursors to a range of important plant metabolites such as the secondary metabolites belonging to the flavonoid/stilbenoid class of compounds. In this study, engineered Escherichia coli containing artificial phenylpropanoid biosynthetic pathways utilizing tyrosine as the initial precursor were established for production of plant-specific metabolites such as ferulic acid, naringenin, and resveratrol. The construction of the artificial pathway utilized tyrosine ammonia lyase and 4-coumarate 3-hydroxylase from Saccharothrix espanaensis, cinnamate/4-coumarate:coenzyme A ligase from Streptomyces coelicolor, caffeic acid O-methyltransferase and chalcone synthase from Arabidopsis thaliana, and stilbene synthase from Arachis hypogaea.
