  Fluorine‐containing amino acids have been used with great success as mechanism‐based inhibitors of pyridoxal phosphate (PLP)‐dependent enzymes, and the influence of fluorine on the conformation of molecules has also been extensively studied and practically exploited. In this study, we sought to use these unique characteristics to probe the reactivity and binding of aspartate decarboxylase (ADC) enzymes

  含氟氨基酸已被用作磷酸吡ido醛（PLP）依赖性酶的基于机理的抑制剂，并且对氟对分子构象的影响也进行了广泛的研究和实际开发。在这项研究中，我们试图利用这些独特的特性来探测天冬氨酸脱羧酶（ADC）酶的反应性和结合力，这是一类丙酮酸依赖性脱羧酶的成员。由于已证明ADC活性对于结核分枝杆菌的毒力至关重要，因此以这种方式获得的信息可用于开发选择性靶向丙酮酰依赖性酶（例如ADC）的抑制剂，而不会影响宿主中PLP依赖性酶。为此，我们合成了大号-赤和大号-苏3- fluoroaspartate异构体并测试它们作为底物和/或所述的抑制剂能力的结核分枝杆菌和大肠杆菌ADC酶。还使用了诱捕和基于MS的结合分析来确认两种异构体都进入了酶的活性位点。我们的研究表明，两种异构体均经过一次脱羧和氟消除反应，生成烯胺产物，该产物可被捕获在活性位点内。有趣的是，烯胺/ ADC复杂，从形式大号-赤（但不是大号-苏）异构体足

• A convenient synthesis of optically pure (2R, 3R)-2, 3- Epoxysuccinyl - dipeptides

  日期：1994.1

  (2R,3R)-trans-Epoxysuccinyl-dipeptides (7a-7d) were synthesized by acylation of dipeptides with the N-hydroxysuccinimide or pentafluorophenyl ester of monoethyl (2R,3R)-trans-epoxysuccinate (6a,6b). A nucleophilic oxirane ring opening by N-hydroxysuccinimide and pentafluorophenol during the preparation of the active esters could not be observed. Subsequent saponification of the monoethyl ester 7a-7d with KOH in ethanolic solution allowed to produce the dipeptide derivatives as potassium salts (8a,8d) which were found to be stable on storage in the cold. The attempts to convert (2R,3R)-trans-epoxysuccinyl-glycyl-proline (7a) into the corresponding (2S,3S)-trans-epithiosuccinyl derivative via an oxygen sulfur exchange reaction with 3-methylbenzothiazole-2-thione failed completely as among the various products of unknown nature formed only the desulfurated fumaryl derivative could be isolated and characterized.

  (2R,3R)-反式-环氧丁二酰二肽(7a-7d)是通过使用单乙基(2R,3R)-反式-环氧丁二酸酯(6a,6b)的N-羟基丁二酰亚胺或五氟苯酯对二肽进行酰化反应合成的。在制备活性酯的过程中，无法观察到由N-羟基丁二酰亚胺和五氟苯酚引发的环氧乙烷环的亲核开环反应。随后，将单乙酯7a-7d与乙醇溶液中的氢氧化钾进行皂化反应，生成了作为钾盐的二肽衍生物(8a,8d)，这些衍生物在冷处保存时表现出稳定性。尝试通过与3-甲基苯并噻唑-2-硫酮进行氧硫交换反应将(2R,3R)-反式-环氧丁二酰甘氨酰脯氨酸(7a)转化为相应的(2S,3S)-反式-环氧丁二硫酰衍生物，但这一尝试完全失败。在生成的各种未知性质产物中，唯一能分离并表征的是脱硫的富马酰衍生物。

• Kinetic Mechanism and Reaction Pathway of Thermus thermophilus Isopropylmalate Dehydrogenase
  作者：Michael C. Pirrung、Hyunsoo Han、David S. Nunn

  日期：1994.5

  Mechanistic studies of isopropylmalate dehydrogenase (IMDH, EC 1.1.1.85),the penultimate enzyme in leucine biosynthesis in bacteria and yeast, have been conducted. It performs two chemical operations, oxidation and decarboxylation, on isopropylmalate to produce alpha-ketoisocaproate. A recombinant enzyme encoded by the leuB gene of the thermophilic bacterium T. thermophilus was used for experiments addressing the kinetic mechanism and chemical pathway of IMDH. A new, asymmetric synthesis of the substrate, (2R,3S)-isopropylmalate, has been developed starting from (2R,3R)tartaric acid. On the basis of kinetic inhibition patterns and exchange experiments, it has been shown that the enzyme follows an ordered sequential bi-tri mechanism, with cofactor NAD binding before substrate beta-isopropylmalate. The release of products occurs in the order CO2, alpha-ketoisocaproate, and NADH. The enzyme catalyzes the exchange of solvent protons into the cu-position of the product, implying that an enol/enolate intermediate is formed. The enzyme conducts two discrete steps: dehydrogenation to isopropyloxaloacetate, which was prepared and shown to be a competent substrate, and decarboxylation to give product.
