    NADPH依赖的2-烷基-3-酮链烷酸还原酶参与嗜麦芽窄食单胞菌的烯烃生物合成的功能表征。
    摘要:
    OleD被证明在嗜麦芽窄食单胞菌的酰基硫酯的烯烃(烯烃)生成中起着关键的还原作用。编码OleD的基因与其他三个基因oleABC聚在一起,并且在各种产生烯烃的细菌中似乎都以与操纵子相同的方向转录。在这项研究中,合成了一系列链长和立体化学不同的底物,并用于阐明OleD的功能作用和底物特异性。我们证明OleD,这是NADP(H)依赖还原酶,是一个同型二聚体,它催化2-烷基-3-酮链烷酸的可逆立体定向还原。用顺-2-癸基-3-羟基十四烷酸观察到的最大催化效率,kcat / K m分别比顺-2-辛基-3-羟基十二酸和顺-2-己基-3-羟基癸酸高5倍和8倍。用顺-2-丁基-3-羟基辛酸和缺少2-烷基的化合物(例如3-酮癸酸和3-羟基癸酸)未观察到OleD活性,这表明2-烷基链对于酶的识别和催化是必要的。使用已知立体化学的底物非对映异构体对和4个对映体纯的2-己基-3-羟基癸酸异构体,OleD被证明对(2

  • A mechanism-based fluorescence transfer assay for examining ketosynthase selectivity

    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。

This flexibility, along with the characterization of catalytic residues, benefits our investigations into the individual roles of the two KAS-III homologues in the heterodimer-catalyzed reactions. The large subunit LstA contains a characteristic Cys-His-Asn triad and likely reacts with C8 acyl-CoA to form an acyl-Cys enzyme intermediate. In contrast, the small

  • Multiple Complexes of Long Aliphatic <i>N</i>-Acyltransferases Lead to Synthesis of 2,6-Diacylated/2-Acyl-Substituted Glycopeptide Antibiotics, Effectively Killing Vancomycin-Resistant Enterococcus

    Teicoplanin A2-2 (Tei)/A40926 is the last-line antibiotic to treat multidrug-resistant Gram-positive bacterial infections, e.g., methicillinresistant Staphylococcus aurcus (MRSA) and vancomycin-resistant enterococcus (VRE). This class of antibiotics is powered by the N-acyltransferase (NAT) Orf11*/Dbv8 through N-acylation on glucosamine at the central residue of Tei/A40926 pseudoaglycone. The NAT enzyme possesses enormous value in untapped applications; its advanced development is hampered largely due to a lack of structural information. In this report, we present eight high-resolution X-ray crystallographic unary, binary, and ternary complexes in order to decipher the molecular basis for NAT's functionality. The enzyme undergoes a multistage conformational change upon binding of acyl-CoA, thus allowing the uploading of Tei pseudoaglycone to enable the acyl-transfer reaction to take place in the occlusion between the N- and C-halves of the protein. The acyl moiety of acyl-CoA can be bulky or lengthy, allowing a large extent of diversity in new derivatives that can be formed upon its transfer. Vancomycin/synthetic acyl-N-acetyl cysteamine was not expected to be able to serve as a surrogate for an acyl acceptor/donor, respectively. Most strikingly, NAT can catalyze formation of 2-N,6-O-diacylated or C6 -> C2 acyl-substituted Tei analogues through an unusual 1,4-migration mechanism under stoichiometric/solvational reaction control, wherein selected representatives showed excellent biological activities, effectively counteracting major types (VanABC) of VRE.
