二氢黄酮醇还原酶(DFR,EC 1.1.1.219)是花色苷合成代谢中的一个关键酶,负责将 3 种二氢黄酮醇还原成无色花色素。在决定植物的花色、叶色、果色和其他经济器官的色泽及其营养品质方面起着重要作用。 二氢黄酮醇还原酶(DFR)作用于二氢槲皮素产生儿茶素,可与香草醛缩合形成红色化合物,在500nm处有特征吸收峰进而得出DFR的酶活性大小。
Dihydroflavonol 4-reductase (DFR, EC 1.1.1.219) is a key enzyme in the anthocyanin biosynthetic pathway, responsible for reducing the three dihydroflavonols to colorless leucoanthocyanidins. It plays a significant role in determining the color of flowers, leaves, and fruits, as well as the色泽 and nutritional quality of other economic organs in plants. Dihydroflavonol 4-reductase (DFR) acts on dihydroquercetin to produce catechin, which can condense with vanillin to form a red compound. This compound has a characteristic absorption peak at 500 nm, allowing the determination of DFR enzyme activity.
