    More than 500 siderophores are known to date, but only three were identified to be aryl-containing hydroxamate siderophores, legonoxamines A and B from Streptomyces sp. MA37, and aryl ferrioxamine 2 from Micrococcus luteus KLE1011.

    Since their discovery, polyketide synthases have received massive attention from researchers hoping to harness their potential as a platform for generating new and improved therapeutics. Despite significant strides toward this end, inherent specificities within the enzymes responsible for polyketide production have severely limited these efforts. We have developed a mechanism-based, fluorescence transfer assay for a key enzyme component of all polyketide synthases, the ketosynthase domain. As demonstrated, this method can be used with both ketosynthase-containing didomains and full modules. As proof of principle, the ketosynthase domain from module 6 of the 6-deoxyerythronolide synthase is examined for its ability to accept a variety of simple thioester substrates. Consistent with its natural hexaketide substrate, we find that this ketosynthase prefers longer, α-branched thioesters and its ability to distinguish these structural features is quite remarkable. Substrate electronics are also tested via a variety of p-substituted aromatic groups. In all, we expect this technique to find considerable use in the field of polyketide biosynthesis and engineering due to its extraordinary simplicity and very distinct visible readout.
    自其发现以来,聚酮合酶一直受到研究人员的极大关注,他们希望利用其潜力作为平台,生成新的和改进的治疗药物。尽管在这方面取得了重大进展,但负责聚酮生产的酶中固有的特定性严重限制了这些努力。我们开发了一种基于机制的、通过荧光传递的测定方法,用于所有聚酮合酶的关键酶组成部分,即酮合酶结构域。如所示,这种方法可以用于含有酮合酶的双结构域和完整模块。作为原理验证,我们检验了来自6-脱氧赤酮酸合酶模块6的酮合酶结构域,以评估其对各种简单硫酯底物的接受能力。与其天然六酮底物一致,我们发现该酮合酶偏好较长的、α-分支的硫酯,并且其区分这些结构特征的能力相当显著。通过各种对位取代的芳香族基团也测试了底物电子性质。总之,我们预计这项技术将在聚酮生物合成和工程领域得到广泛应用,因为它极其简单且具有非常明显的可见输出。

    of congeners. This first structural analysis of loading ATs from modular PKSs revealed the molecular basis for the relaxed substrate specificity. Residues important for substrate binding and discrimination were predicted by modeling a substrate into the active site. A mutant with altered specificity toward a panel of synthetic substrate mimics was generated by site-directed mutagenesis of the active
    模块化聚酮化合物合酶(PKS)的负载酰基转移酶(AT)结构域控制掺入聚酮化合物中的起始单元的选择,因此是模块化PKSs工程的有吸引力的目标。在这里,我们报道了来自阿维菌素模块化PKS的负载AT的结构和生化特征,阿维菌素模块化PKS接受40多种羧酸作为一系列同类物生物合成的替代起始单元。从模块化PKS加载AT的首次结构分析揭示了轻松的底物特异性的分子基础。通过将底物建模到活性位点,可以预测对底物结合和识别重要的残基。通过活性位点残基的定点诱变产生了对一组合成底物模拟物具有改变的特异性的突变体。在基板的C-2位置呈S构型。总之,这些结果为通过装载模块化PKS的AT域的活性位点工程进行聚酮化合物的区域特定修饰奠定了基础。

    engineered biosynthesis of novel allyl group-modified FK506 analogues, 36-fluoro-FK520 and 36-methyl-FK506, the latter of which exhibits improved neurite outgrowth activity. This unique feature of FK506 biosynthesis, in which a dedicated PKS provides an atypical extender unit for the main modular PKS, illuminates a new strategy for the combinatorial biosynthesis of designer macrolide scaffolds as well
