  • Biochemical Investigation of Pikromycin Biosynthesis Employing Native Penta- and Hexaketide Chain Elongation Intermediates
    作者:Courtney C. Aldrich、Brian J. Beck、Robert A. Fecik、David H. Sherman
    DOI:10.1021/ja042592h
    日期:2005.6.1
    the pikromycin (Pik) polyketide synthase to generate 12- and 14-membered ring macrolactones presents an opportunity to explore the fundamental processes underlying polyketide synthesis, specifically the mechanistic details of chain extension, keto group processing, acyl chain release, and macrocyclization. We have synthesized the natural pentaketide and hexaketide chain elongation intermediates as N-acetyl
    pikromycin (Pik) 聚酮化合物合成酶生成 12 和 14 元环大环内酯的独特能力为探索聚酮化合物合成的基本过程提供了机会,特别是链延伸、酮基加工、酰基链释放和大环化。我们合成了天然五肽和六酮链延长中间体作为 N-乙酰半胱胺 (NAC) 酯,并将它们用作与工程化 PikAIII+TE 以及与天然 PikAIII(模块 5)和 PikAIV(模块 6)组合进行体外转化的底物) 多功能蛋白质。这项研究直接证明了这些单体模块在催化一个或两个扩链反应、酮基加工步骤、酰基-ACP 释放、环化生成10-脱氧甲炔内酯和内酯。结果揭示了 Pik 单体对其天然聚酮化合物底物的极大偏好,并提供了与先前使用非天然二酮 NAC 酯底物的研究的重要比较分析。
  • Linear Aglycones Are the Substrates for Glycosyltransferase DesVII in Methymycin Biosynthesis:  Analysis and Implications
    作者:Chai-Lin Kao、Svetlana A. Borisova、Hak Joong Kim、Hung-wen Liu
    DOI:10.1021/ja058433v
    日期:2006.5.1
    The two essential structural components of macrolide antibiotics are the polyketide aglycone and the appended sugars. The aglycone formation is catalyzed by polyketide synthase (PKS), and glycosylation is catalyzed by an appropriate glycosyltransferase. Although it has been shown that glycosylation occurs after the cyclic aglycone is released from PKS, it is not known whether the acyl carrier protein
    大环内酯类抗生素的两个基本结构成分是聚酮苷元和附加糖。苷元的形成由聚酮合酶 (PKS) 催化,糖基化由适当的糖基转移酶催化。虽然已经表明糖基化发生在环状苷元从 PKS 释放后,但尚不清楚与酰基载体蛋白 (ACP) 结合的线性聚酮链是否也可以被相应的糖基转移酶处理。为了探索这种可能性,以线性形式化学合成了作为 N-乙酰半胱胺 (NAC) 酯的糖苷配基 10-脱氧甲炔内酯,它是甲霉素和新甲霉素的前体。随后在专用糖基转移酶 DesVII 和激活剂 DesVIII 存在下与 TDP-d-desosamine 孵育,产生极性更强的产物,其高分辨率质量与预期的糖基化产物一致。该研究首次证明大环内酯糖基转移酶也可以识别和加工其大环内酯底物的线性前体,但活性降低但可测量。
  • Frontiers and Opportunities in Chemoenzymatic Synthesis
    作者:Jonathan D. Mortison、David H. Sherman
    DOI:10.1021/jo101124n
    日期:2010.11.5
    Natural product biosynthetic pathways have evolved enzymes with myriad activities that represent an expansive array of chemical transformations for constructing secondary metabolites. Recently, harnessing the biosynthetic potential of these enzymes through chemoenzymatic synthesis has provided a powerful tool that often rivals the most sophisticated methodologies in modern synthetic chemistry and provides new opportunities for accessing chemical diversity. Herein, we describe our research efforts with enzymes from a broad collection of biosynthetic systems, highlighting recent progress in this exciting field.
  • Macrolactonization to 10-deoxymethynolide catalyzed by the recombinant thioesterase of the picromycin/methymycin polyketide synthase
    作者:Weiguo He、Jiaquan Wu、Chaitan Khosla、David E. Cane
    DOI:10.1016/j.bmcl.2005.09.077
    日期:2006.1
    The recombinant thioesterase (TE) domain of the picromycin/methymycin synthase (PICS) catalyzes the macrolactonization of 3, the N-acetylcysteamine thioester of seco-10-deoxymethynolide to generate 10-deoxymethynolide (1) with high efficiency. By contrast, 4, the 7-dihydro derivative of seco-thioester 3, undergoes exclusive hydrolysis by PICS TE to seco-acid 5. The recombinant TE domain of 6-deoxyerythronolide B synthase (DEBS TE) shows the same reaction specificity as PICS TE, but with significantly lower activity. (c) 2005 Elsevier Ltd.
