Enzymatic Approaches in Polyphenol Synthesis

Polyphenols are naturally occurring compounds found in fruits, vegetables, tea, wine and other plant-based products, which are particularly well known these days for their strong antioxidant properties and potential therapeutic effects. Enzymatic approaches have emerged as a promising alternative for polyphenol synthesis, offering high specificity, mild reaction conditions, and environmentally friendly processes. Key enzymes such as phenol oxidases, peroxidases and glycosyltransferases play important roles in polyphenol synthesis in the case of different types of furaltio. Phenol oxidases catalyze the oxidation of phenolic substrates to form reactive quinones, which can then undergo polymerization or react with or assist other nucleophiles to form complex polyphenolic structures. Peroxidases use hydrogen peroxide to facilitate the polymerization of phenolic compounds, producing a diverse array of polyphenols with varying degrees of polymerization and functional properties. The use of whole cell biocatalysis and recombinant DNA technology has expanded the toolkit of polyphenol synthesis, enabling the engineering of microbial hosts to overexpress specific enzymes or metabolic pathways that enhance polyphenol production. Recent advances in enzyme engineering and immobilization techniques resulting from technology development have further improved the efficiency and applicability of enzymatic polyphenol synthesis.
