许多铁硫蛋白的活性中心都是铁硫原子簇化合物。如植物铁氧还蛋白,皮质铁氧还蛋白和假单孢氧还蛋白的活心位置是Fe_2S_2原子簇化合物。固氮酶的铁蛋白活性中心是Fe_4S_4原子簇化合物。固氮酶的钼铁蛋白中,除Mo—Fe—S原子簇、Fe_4S_4原子簇外,还有Fe_2S_2原子簇等等。铁硫原子簇化合物的主要特点是容易发生氧化还原反应,因而能传递电子。它们在生物体中所起的正是活化和传递电子的作用。所以,铁硫原子簇化合物的合成、结构和性质研究具有重要的仿生意义。
Many of the iron-sulfur protein active centers are iron-sulfur cluster compounds. Such as plant ferredoxin, cortical ferredoxin and pseudomortioxin position is Fe2S2 atomic cluster compounds. Ferritin ferritin activity center is Fe_4S_4 cluster compounds. In the nitrogenase-containing molybdenum ferritin, in addition to Mo-Fe-S cluster, Fe 4S 4 cluster, Fe 2 S 2 cluster and so on. The main feature of iron-sulfur cluster compounds is their susceptibility to oxidation-reduction reactions, which can transfer electrons. What they play in the organism is the activation and the transfer of electrons. Therefore, the synthesis, structure and properties of Fe-S cluster compounds have important biomimetic significance.
