  • Synthesis of 2-<i>O</i>-Methyl Ether and 1-Carboxamide Derivatives of (2<i>R</i>,3<i>S</i>)-3-Isopropylmalic Acid and Their Interaction with Thermophilic 3-Isopropylmalate Dehydrogenase

    To get a closer insight into the substrate recognition of thermostable 3-isopropylmalate dehydrogenase (IPMDH) derived from Thermus thermophilus HB8, two analogs of the natural substrate, (2R,3S) 3-isopropylmalic acid (IPM) were synthesized according to the chiral transcription methodology which we have recently developed, and the kinetics of the enzyme reaction were analyzed. 2-O-methyl IPM was found to be inactive as a substrate but to function as an uncompetitive inhibitor, which suggests that, although it is the site of oxidation by NAD+, 2-O-methyl IPM was incorporated into one of the active sites of the homodimeric enzyme. The hydroxyl group at C-2 was not essential to the substrate recognition by IPMDH. The 1-carboxamide derivative of IPM was inactive, both as a substrate and as an inhibitor. This clearly implies the prime importance of electrostatic interaction between the C-1 carboxylate of IPM and a cationic function (probably a guanidino group of Arg-104) of the enzyme for the recognition of IPM.
    为了更深入地了解嗜热菌HB8中热稳定3-异丙基丙二酸脱氢酶(IPMDH)对底物的识别,我们根据最近开发的手性转录方法合成了两种天然底物的类似物(2R,3S)3-异丙基丙二酸IPM),并分析了酶反应的动力学。我们发现2-O-甲基IPM作为底物不活跃,但可以作为非竞争性抑制剂发挥作用,这表明尽管它是NAD+的氧化位点,但2-O-甲基IPM被整合到了同源二聚酶的一个活性位点中。IPMDH识别底物时,C-2的羟基不是必需的。IPM的1-羧酰胺衍生物作为底物和抑制剂都不活跃。这清楚地表明,IPM的C-1羧酸与酶的阳离子功能(可能是Arg-104的基)之间的静电相互作用对于IPM的识别至关重要。
