Acetyl-coenzyme A (CoA) carboxylase from maize (Zea mays L.) is inhibited by nanomolar concentrations of both haloxyfop, an aryloxyphenoxypropionate, and tralkoxydim, a cyclohexanedione herbicide. These results suggest that acetyl-CoA carboxylase, which catalyzes the first committed step in fatty acid biosynthesis, may be the target of these herbicides, contrary to an earlier report suggesting that aryloxyphenoxypropionate herbicides do not inhibit acetyl-CoA carboxylase.
来自玉米(Zea mays L.)的乙酰辅酶A(CoA)羧化酶受到纳摩尔浓度的氟吡甲禾灵(一种芳氧苯氧丙酸酯)和炔草酯(一种环己二酮类除草剂)的抑制。这些结果表明,催化脂肪酸生物合成中首个关键步骤的乙酰辅酶A羧化酶可能是这些除草剂的作用靶标,这与早期一份认为芳氧苯氧丙酸酯类除草剂不会抑制乙酰辅酶A羧化酶的报告相反。
