  • Synthesis, characterization, and enzymic conversion of nonhydrolysable analogues of propionylcoenzyme A
    作者:Yimin Zhao、Martina Michenfelder、János Rétey
    DOI:10.1139/v94-025
    日期:1994.1.1

    We describe the synthesis of three novel analogues of propionyl-coenzyme A, in which the sulfur atom has been replaced by methylene, ethylene, and thiomethylene, respectively. All three analogues, propionyl-dethia(carba)-CoA (1), propionyl-dethia(dicarba)-CoA (2), and S-(2-oxobutanyl)-CoA (3) were characterized by 1H and 31P NMR spectroscopy and FAB mass spectrometry. Propionyl-CoA–oxaloacetate transcarboxylase from Propionibacterium shermanii accepted the novel analogues as substrates and carboxylated them to the corresponding methylmalonyl-CoA analogues (4–6). The latter were further converted into the succinyl-CoA analogues by the coenzyme-B12-dependent methylmalonyl-CoA mutase from the same organism. The succinyl-CoA analogues, succinyl-dethia(carba)-CoA (7), succinyl-dethia(dicarba)-CoA (8), and 4-carboxy(2-oxobutanyl)-CoA (9) were obtained on a preparative scale and their Michaelis constants (Km) with methylmalonyl-CoA mutase were determined to be 0.136, 2.20, and 0.132 mM, respectively (Km for succinyl-CoA is 0.025 mM). The Vmax values for 7, 8, and 9 are 1.1, 0.013, and 0.0047 µmol min−1 U−1, respectively (Vmax for succinyl CoA is 1.0). The utility of the novel coenzyme A analogues in enzyme mechanistic studies is discussed.

    我们描述了三种新的丙酰辅酶A类似物的合成,其中原子分别被亚甲基、乙烯基亚甲基取代。这三种类似物,丙酰-去(碳)-辅酶A(1)、丙酰-去(二碳)-辅酶A(2)和S-(2-氧丁酰)-辅酶A(3)通过1H和31P核磁共振光谱和FAB质谱进行了表征。来自谢尔曼丙酸杆菌的丙酰辅酶A-草酰乙酸转羧酶接受了这些新的类似物作为底物,并将它们羧化为相应的甲基丙二酰辅酶A类似物(4-6)。后者进一步由同一生物体内的辅酶B12依赖的甲基丙二酰辅酶A异构酶转化为琥珀酰辅酶A类似物。在制备规模上获得了琥珀酰-去(碳)-辅酶A(7)、琥珀酰-去(二碳)-辅酶A(8)和4-羧基(2-氧丁酰)-辅酶A(9),并确定了它们与甲基丙二酰辅酶A异构酶的米氏常数(Km)分别为0.136、2.20和0.132 mM(琥珀酰辅酶A的Km为0.025 mM)。7、8和9的Vmax值分别为1.1、0.013和0.0047 µmol min−1 U−1琥珀酰辅酶A的Vmax为1.0)。讨论了新型辅酶A类似物在酶机理研究中的实用性。
