Key-enzymes involved in the biosynthesis of resveratrol-based stilbenes in Vitis spp.: a review
Polyphenols are a large class of plant specialized metabolites with interesting biological properties. Among them, the stilbene phytoalexins are particularly abundant in grapevine gaining considerable applications in the cosmetic and nutraceutical industry. The well-studied stilbene biosynthetic pathway uses phenylalanine to generate resveratrol, the primary stilbene core synthetized in grapevine. A set of enzymes further metabolize resveratrol producing a diversity of stilbenes with different properties, activities and stabilities. In grapevine, 13 enzymes have been identified with the ability to use resveratrol as a substrate, including ten peroxidases, two glycosyltransferases and one O-methyltransferase. Peroxidases and methyltransferases are the most studied enzymes in grapevine, especially under stress conditions while the role of plant laccases and hydroxylases in stilbene metabolism is still poorly described. This article provides an overview of the key enzymes involved in the synthesis of resveratrol-based derivatives in Vitis spp. Perspectives to identify new enzymes are discussed, which could be further used for stilbene bioproduction using biotechnologies.
期刊介绍:
Phytochemistry Reviews is the sole review journal encompassing all facets of phytochemistry. It publishes peer-reviewed papers in six issues annually, including topical issues often stemming from meetings organized by the Phytochemical Society of Europe. Additionally, the journal welcomes original review papers that contribute to advancing knowledge in various aspects of plant chemistry, function, biosynthesis, effects on plant and animal physiology, pathology, and their application in agriculture and industry. Invited meeting papers are supplemented with additional review papers, providing a comprehensive overview of the current status across all areas of phytochemistry.
