The viability of plants relies on molybdenum, which after binding to the organic moiety of molybdopterin forms the molybdenum cofactor (Moco) and acquires remarkable redox properties. Moco is in the active site of critical molybdoenzymes, which use to work as small electron transport chains and participate in N and S metabolism, hormone biosynthesis, toxic compound transformations and other important processes not only in plants but also in all the other kingdoms of life. Molybdate metabolism in plants is reviewed here, with special attention to two main aspects, the different molybdate transporters that with a very high affinity participate in molybdenum acquisition and the recently discovered Moco enzyme amidoxime-reducing component. Their functionality is starting to be understood.
植物的生存能力依赖于钼，钼与钼喋呤的有机部分结合后形成钼辅因子（Moco），并获得显著的氧化还原性质。Moco 位于关键钼酶的活性部位，这些酶作为小型电子传递链发挥作用，并参与氮和硫代谢、激素生物合成、有毒化合物转化以及其他重要过程，不仅在植物中，而且在所有其他生命王国中都是如此。本文综述了植物中的钼酸盐代谢，特别关注两个主要方面，即具有非常高亲和力的不同钼酸盐转运蛋白参与钼的获取，以及最近发现的 Moco 酶酰胺肟还原成分。它们的功能开始被理解。
