The enzyme C-glycosyltransferase (CGT) from Pueraria Mirifica Var. Lobata is involved in the biosynthesis of isoflavonoids. CGT catalyzes the dehydration of 2-hydroxyisoflavonones, facilitating the formation of isoflavonoid compounds.

Proof of Function

This part was used in a composite part along with other key enzymes in the isoflavonoid biosynthetic pathway and was agroinfiltrated into N. benthamiana using Agrobacterium tumefaciens.

The enzyme C-glycosyltransferase (CGT) from Pueraria Mirifica Var. Lobata is involved in the glycosylation of flavonoids by attaching sugar molecules to the flavonoid backbone through C-glycosylation. This process is important in the biosynthesis of glycosylated flavonoids, which have enhanced stability and solubility in plants. The CGT part is 1410 base pairs long and is designed to be compatible with several assembly standards, making it suitable for the use in synthetic biology projects to express this enzyme in hose organisms such as Nicotiana benthamiana for further research on flavonoid biosynthesis.

Figure 3: HPLC Chromatogram showing the detection of puerarin, daidzin, genistin, iso-vitexin, daidzien and genistein in transformed Nicotiana benthamiana samples

After transformation, the modified plants were tested for isoflavonoid production using High-Performance Liquid Chromatography (HPLC). The chromatogram shows the amounts of each target isoflavonoid: puerarin, daidzein, and genistein with the first peak, observed at around 16.0 minutes, representing puerarin, followed by a peak at approximately 17.0 minutes, which corresponds to daidzin. Further along, a peak at 22.0 minutes is attributed to genistin. Traces of all three compounds were detected in N. benthamiana, a plant that does not naturally produce any of these because it lacks the enzymes needed to do so. This shows that the sequence for CGT did function as intended because if it hadn't then the pathway wouldn't have progressed further and produced these isoflavonoids.
