    Enediyne Polyketide Synthases Stereoselectively Reduce the β-Ketoacyl Intermediates to β-d-Hydroxyacyl Intermediates in Enediyne Core Biosynthesis
    摘要:
    PKSE biosynthesizes an enediyne core precursor from decarboxylative condensation of eight malonyl-CoAs. The KR domain of PKSE is responsible for iterative β-ketoreduction in each round of polyketide chain elongation. KRs from selected PKSEs were investigated in vitro with β-ketoacyl-SNACs as substrate mimics. Each of the KRs reduced the β-ketoacyl-SNACs stereoselectively, all affording the corresponding β-D-hydroxyacyl-SNACs, and the catalytic efficiencies (k(cat)/K(M)) of the KRs increased significantly as the chain length of the β-ketoacyl-SNAC substrate increases.

  • Understanding Programming of Fungal Iterative Polyketide Synthases: The Biochemical Basis for Regioselectivity by the Methyltransferase Domain in the Lovastatin Megasynthase

    Highly reducing polyketide synthases (HR-PKSs) from fungi synthesize complex natural products using a single set of domains in a highly programmed, iterative fashion. The most enigmatic feature of HR-PKSs is how tailoring domains function selectively during different iterations of chain elongation to afford structural diversity. Using the lovastatin nonaketide synthase LovB as a model system and a
    来自真菌的高度还原性聚酮化合物合酶 (HR-PKS) 以高度程序化的迭代方式使用一组域合成复杂的天然产物。HR-PKS 最神秘的特征是在链伸长的不同迭代过程中,剪裁域如何有选择地发挥作用,以提供结构多样性。使用洛伐他汀九肽合酶 LovB 作为模型系统和各种酰基底物,我们表征了 LovB 甲基转移酶 (MT) 域的底物特异性。我们表明,虽然 MT 结构域对不同的 β-酮酰基基团显示出甲基化活性,但在链长和功能化方面,它对其自然编程的 β-酮-二烯基四酮底物具有异常选择性。伴随酮还原酶 (KR) 结构域的表征显示出对不同 β-酮酰基基团更广泛的底物特异性。我们的研究表明,相对于其他竞争域的转化率,通过对特定底物的更高动力学效率来实现通过定制域(例如 MT)进行的选择性修饰。
