  • Mechanism and Stereospecificity of a Fully Saturating Polyketide Synthase Module: Nanchangmycin Synthase Module 2 and Its Dehydratase Domain
    作者:Xun Guo、Tiangang Liu、Chiara R. Valenzano、Zixin Deng、David E. Cane

    日期:2010.10.27
    Recombinant nanchangmycin synthase module 2 (NANS module 2), with the thioesterase domain from the 6-deoxyerythronolide B synthase (DEBS TE) appended to the C-terminus, was cloned and expressed in Escherichia coli. Incubation of NANS module 2+TE with (+/-)-2-methyl-3-keto-butyryl-N-acetylcysteamine thioester (1), the SNAC analog of the natural ACP-bound substrate, with methylmalonyl-CoA (MM-CoA) in the absence of NADPH gave 3,5,6-trimethy1-4-hydroxypyrone (2), identified by direct comparison with synthetic 2 by radio-TLC-phosphorimaging and LC-ESI(+)-MS-MS. The reaction showed K(cat) 0.5 +/- 0.1 min(-1) and K(m)(1) 19 +/- 5 mM at 0.5 mM MM-CoA and k(cat)(app) 0.26 +/- 0.02 min(-1) and K(m)(MM-CoA) 0.11 +/- 0.02 mM at 8 mM 1. Incubation in the presence of NADPH generated the fully saturated triketide chain elongation product as a 5:3 mixture of (2S,4R)-2,4-dimethy1-5-ketohexanoic acid (3a) and the diastereomeric (2S, 4S)-3b. The structure and stereochemistry of each product was established by comparison with synthetic 3a and 3b by a combination of radio-TLC-phosphorimaging and LC-ESI(-)-MS-MS, as well as chiral capillary GC-MS analysis of the corresponding methyl esters 3a-Me and 3b-Me. The recombinant dehydratase domain from NANS module 2, NANS DH2, was shown to catalyze the formation of an (E)-double bond by syndehydration of the ACP-bound substrate anti-(2R,3R,4S,5R)-2,4-dimethyl-3,5-dihydroxyheptanoyl-ACP6 (4), generated in situ by incubation of (2S,3R)-2-methyl-3-hydroxypentanoyl-SNAC (5), methylmalonyl-CoA, and NADPH with the recombinant [KS6][AT6] didomain and ACP6 from DEBS module 6 along with the ketoreductase from the tylactone synthase module 1 (TYLS KR1). These results also indirectly establish the stereochemistry of the reactions catalyzed by the KR and enoylreductase (ER) domains of NANS module 2.
  • Synthetic Studies on Borrelidin:  Enantioselective Synthesis of the C1−C12 Fragment
    作者:Binh G. Vong、Sunny Abraham、Alan X. Xiang、Emmanuel A. Theodorakis
    DOI:10.1021/ol034243i
    日期:2003.5.1
    [structure: see text] An efficient, enantioselective synthesis of the C1-C12 fragment 2 of borrelidin is presented. Construction of the "skipped" polymethylene chain of 2 was accomplished by iteration of Myers' alkylation, while formation of the C3 stereocenter was achieved by Roush's asymmetric allylboration methodology.
    [结构:见正文]提出了一种有效的对映体合成硼瑞林定的C1-C12片段2的方法。通过迈尔斯的烷基化反应完成“跳过”的2亚甲基链的构建,而C3立体中心的形成则通过Roush的不对称烯丙基硼化方法完成。
