  摘要：

  Alb29 是一种 α-氧代胺合酶，参与Streptomyces albogriseolus MGR072中的 albogrisin 生物合成，被表征并负责将l-谷氨酸掺入酰基辅酶 A 底物。结合Alb29和Mgr36（一种酰基辅酶A连接酶），建立了一锅法合成七个α-氨基酮。当这些α-氨基酮分别加入alb29敲除菌株Δalb29时，观察到具有不同侧链的albogrisin类似物。

  Labeling Lysine Acetyltransferase Substrates with Engineered Enzymes and Functionalized Cofactor Surrogates

  摘要：

  Elucidating biological and pathological functions of protein lysine acetyltransferases (KATs) greatly depends on the knowledge of the dynamic and, spatial localization of their enzymatic targets in the cellular proteome. We report the design and application of chemical probes for facile labeling and detection of substrates of the three major human KAT enzymes. In this approach, we create engineered KATs in junction with synthetic Ac-CoA surrogates to effectively label KAT, substrates even in the presence of competitive nascent cofactor acetyl-CoA. The functionalized and transferable acyl moiety of the Ac-CoA analogs further allowed the labeled substrates to be probed with alkynyl or azido-tagged fluorescent reporters by the copper-catalyzed azide-alkyne cycloaddition. The synthetic cofactors, in combination with either native or rationally engineered KAT enzymes, provide a versatile chemical biology strategy to label and profile cellular targets of KATs at the proteomic level.

  Protein acetylation is a key post-translational modification that regulates diverse biological activities in eukaryotes. Here we report bioorthogonal chemical reporters that enable direct in-gel fluorescent visualization and proteome-wide identification of acetylated proteins via Cu(I)-catalyzed azide-alkyne cycloaddition, often termed "click chemistry". We demonstrate that two alkynyl-acetyl-CoA analogues

  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.
