Many plants accumulate malonate, but it was shown earlier that malonate does not accumulate as a deadend product of metabolism in soybean (Glycine max v. Hodgson tissues. The metabolism of malonate in the soybean plant at the whole tissue and enzymic level was followed, and the pathway of malonate biosynthesis in young soybean root tissue was shown to be via acetyl-coenzyme A carboxylase.
许多植物会积累丙二酸盐,但此前的研究表明,在大豆(Glycine max v. Hodgson 组织)中,丙二酸盐并不会作为代谢的无出路产物积累。我们跟踪了大豆组织的整体代谢和酶水平的丙二酸盐代谢,结果表明,在幼大豆根组织中,丙二酸盐的生物合成途径是通过乙酰辅酶 A 羧化酶。
