General Information

General Information Comment Organism
metabolism the enzyme is involved in the proposed biosynthetic pathway of C-glucosylflavones in buckwheat, overview. It starts with the hydroxylation of the 2-position of flavanone, which is the intermedixadate product of flavonol biosynthesis. The produced 2-hydroxyflavanone is in equilibrium with one of its open-circular forms (2',4',6'-trihydroxyacetophenone-like structure, dibenzoylxadmethane form), which is C-glucosylated by CGT. The formed C-glucoside is also in equilibrium with its two closed-circular forms, that is, 2-hydroxyflavanone 6-C-glucoside and 8-C-glucoside, because the sugar moiety of the open-circular form of C-glucoside can be rotated. They are then enzymatically dehydrated to produce two C-glucosylflavones Fagopyrum esculentum
physiological function FeCGT enxadzymes (UGT708C1 and UGT708C2) show C-glucosylation activity toward 2-hydroxyflavanones and related compounds having a 2',4',6'-trihydroxyacetophenone-like structure but not toward flavones or flavonols, indicating that the open-circular form of 2-hydroxyflavanones is their substrate Fagopyrum esculentum
