Abstract

Abstract:

Phenylpropanoic acids are important phenylpropanoid compounds, which are natural organic acids containing the C₆-C₃ unit, including phenylacrylic acid and phenyllactic acid compounds. Many phenylpropanoic acids have activities in antioxidation, antibacteria, antitumors, antivirus, anti-inflammation, immunity enhancement, reducing blood lipids, and treating cardiovascular diseases. Phenylpropanoic acids are widely used in food, medicine, flavor, cosmetics, agriculture, and so forth. In plants, phenylpropanoids are synthesized from L-phenylalanine or L-tyrosine derived from the shikimate pathway. To overcome the drawbacks of their extract from plants, biotechnological production is a good alternative. With advances in metabolic engineering and synthetic biology, many microorganisms have been engineered to produce phenylpropanoic acids and their derivatives. Herein, we systematically and comprehensively review recent advancements in the production of phenylpropanoic acids and their derivatives by metabolic engineered microorganisms. These compounds include cinnamic acid, styrene, p-coumaric acid, p-hydroxystyrene, p-coumaroyl shikimate, caffeic acid, chlorogenic acid, 3,4-hydroxystyrene, ferulic acid, curcumin, L-DOPA, phenyllactic acid, p-hydroxyphenyllactic acid, salvianic acid A, and rosmarinic acid. Then, some main synthetic biology strategies for the microbial production of the aromatics are summarized. Finally, future perspectives about engineering microorganisms for producing phenylpropanoids are discussed. Some strategies are proposed: 1) tolerance engineering using biosensor-based adaptive laboratory evolution; 2) oxidative engineering; 3) modular coculture engineering; 4) systems metabolic engineering.

Key words: engineered microorganisms, phenylpropanoic acids and their derivatives, metabolic engineering, synthetic biology, biosynthesis, strain construction
