Some flavonoids are considered as beneficial compounds because they exhibit anticancer or antioxidant activity. In higher plants, flavonoids are secondary metabolites that are derived from phenylpropanoid biosynthetic pathway. A large number of phenylpropanoids are generated from p-coumaric acid,

Curcuminoids are phenylpropanoids with high pharmaceutical potential. Herein, we report an engineered artificial pathway in Escherichia coli to produce natural curcuminoids through caffeic acid. Arabidopsis thaliana 4-coumaroyl-CoA ligase and Curcuma longa diketide-CoA synthase (DCS) and curcumin

We report the design and characterization of photoactive yellow protein (PYP)-blue fluorescent protein (mTagBFP) fusion constructs that permit the direct assay of reconstitution and function of the PYP domain. These constructs allow for in vivo testing of co-expression systems for enzymatic

Resveratrol is a naturally occurring defense compound produced by a limited number of plants in response to stresses. Besides cardiovascular benefits, this health-promoting compound has been reported to extend life spans in yeasts, flies, worms, and fish. To biosynthesize resveratrol de novo,

BACKGROUND The aromatic compounds cinnamic acid (CA) and p-hydroxycinnamic acid (pHCA) are used as flavoring agents as well as precursors of chemicals. These compounds are present in plants at low concentrations, therefore, complex purification processes are usually required to extract the product.

Flavonoids are important plant-specific secondary metabolites synthesized from 4-coumaroyl coenzyme A (CoA), derived from the general phenylpropanoid pathway, and three malonyl-CoAs. The synthesis involves a plant type III polyketide synthase, chalcone synthase. We report the cloning and

BACKGROUND Flavonoids comprise a large family of secondary plant metabolic intermediates that exhibit a wide variety of antioxidant and human health-related properties. Plant production of flavonoids is limited by the low productivity and the complexity of the recovered flavonoids. Thus to overcome

BACKGROUND Oats contain hydroxycinnamoyl anthranilates, also named avenanthramides (Avn), which have beneficial health properties because of their antioxidant, anti-inflammatory, and antiproliferative effects. The microbial production of hydroxycinnamoyl anthranilates is an eco-friendly alternative

Cinnamyl alcohol glycosides (CAGs) are key active ingredients of the precious medicinal plant Rhodiola rosea L., which has diverse pharmacological activities. The quality of R. rosea extracts is standardized to the contents of rosavin, a cinnamyl alcohol disaccharide, along with

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

Flavonoids are valuable natural products derived from the phenylpropanoid pathway. The objective of this study was to create a host for the biosynthesis of naringenin, the central precursor of many flavonoids. This was accomplished by introducing the phenylpropanoid pathway with the genes for

Resveratrol is a natural antioxidant compound, used as food supplement and cosmetic ingredient. Microbial production of resveratrol has until now been achieved by supplementation of expensive substrates, p-coumaric acid or aromatic amino acids. Here we engineered the yeast Saccharomyces cerevisiae

Background: Resveratrol is a plant secondary metabolite with diverse, potential health-promoting benefits. Due to its nutraceutical merit, bioproduction of resveratrol via microbial engineering has gained increasing attention and provides
