The present invention relates to a method for producing optically active IHOG, which can in turn be used for the production of monatin. The present invention further relates to a method for producing optically active monatin, and aldolase used for these methods. As such, the present invention enables the synthesis of 4-(Indole-3-ylmethyl)-4-hydroxy-2-oxoglutaric acid with high optical purity, which is useful as an intermediate in the synthesis of optically active monatin, from indole pyruvic acid and pyruvic acid (or oxaloacetic acid).
本发明涉及一种制备光学活性IHOG的方法,该方法可用于生产莫纳丁。本发明还涉及一种制备光学活性莫纳丁的方法,以及用于这些方法的醛酸酯酶。因此,本发明使得从吲哚丙酮酸和丙酮酸(或草酰乙酸)制备出具有高光学纯度的4-(吲哚-3-基甲基)-4-羟基-2-酮戊二酸成为可能,该化合物在光学活性莫纳丁的合成中作为中间体具有重要用途。
