  名称：

  Fingerprint lipolytic enzymes with chromogenic p-nitrophenyl esters of structurally diverse carboxylic acids

  摘要：

  A series of structurally diverse chromogenic esters, including a new compound (4-nitrophenyl 2-methylpentanoate), has been synthesized, constituting an array of 17 substrates which could be applied to rapidly fingerprint the activity of lipases or esterases to reveal their substrates specificity and functional characteristics. Combined with genetic technology such as "data mining" and directed evolution, such fingerprints might be a promising platform for discovery of potentially useful enzymes in industrial application. The fingerprint of commercially available Lipase-B from Candida antarctica as a model enzyme was first measured to confirm the reliability of this method. Then three new enzymes mined from genomic libraries were successfully fingerprinted, revealing the functional characteristics of those enzymes. Among them, the enzyme SrfAD was founded with specific substrate preference towards cycloalkyl carboxylic esters and aromatic esters, making it more promising in synthetic utilities than other tested enzymes.

  Esterase antibody 522c2, the first example of a catalytic antibody specifically programmed to control the reactivity of functional groups on the side chain of tyrosine, accelerates the hydrolysis of benzoate esters of L-tyrosine and tyrosine-containing dipeptides by a factor of 104 and is moderately active against other benzoate esters.

  Enzymatic stereodivergent synthesis to access all possible product stereoisomers bearing multiple stereocenters is relatively undeveloped, although enzymes are being increasingly used in both academic and industrial areas. When two stereocenters and thus four stereoisomeric products are involved, obtaining stereodivergent enzyme mutants for individually accessing all four stereoisomers would be ideal

  尽管酶越来越多地用于学术和工业领域，但酶促立体发散合成以获取所有可能的具有多个立体中心的产品立体异构体相对不发达。当涉及两个立体中心和四个立体异构产物时，获得立体发散酶突变体以单独访问所有四种立体异构体将是理想的。尽管在一般酶的定向进化方面取得了重大成功，但将一种酶立体发散工程化为四种高度立体互补的变体以获得带有多个立体中心的立体异构体的完整补充仍然是一个挑战。使用南极念珠菌脂肪酶 B (CALB) 作为模型，我们将这种酶的蛋白质工程报告为四种高度立体互补的变体，这些变体是在有机溶剂中外消旋酸和外消旋醇之间的酯交换反应中获得所有四种立体异构体所需的。通过生成和筛选每种异构体的少于 25 个变体，我们对模型反应中所有四种可能的立体异构体实现了 >90% 的选择性。这一困难的壮举是通过在酶结合口袋内衬的位点开发一种称为“集中合理迭代位点特异性诱变”（FRISM）的策略来完成的。使用一组有限的合

  An isothiourea-catalyzed enantioselective Michael addition of aryl ester pronucleophiles to vinyl bis-sulfones via C(1)-ammonium enolate intermediates has been developed. This operationally simple method allows the base-free functionalization of aryl esters to form α-functionalized products containing two contiguous tertiary stereogenic centres in excellent yield and stereoselectivity (all ≥99:1 er)

  已经开发了一种异硫脲催化的对映体，通过C（1）-烯醇铵中间体将芳基酯原核糖对映体选择性迈克尔加成。这种操作简单的方法可以使芳基酯进行无碱官能化，从而以优异的收率和立体选择性（均≥99：1 er）形成包含两个连续的三级立体异构中心的α-官能化产物。该方法成功的关键是芳基氧化物的多功能作用，该芳基氧化物在催化周期内作为离去基团，布朗斯台德碱，布朗斯台德酸和路易斯碱起作用。已经进行了全面的力学研究，包括可变时间归一化分析（VTNA）和同位素同位素竞争实验。这些研究已经确定（i）所有反应物的顺序；（ii）限制营业额的迈克尔加法步骤，
• Removing the Active-Site Flap in Lipase A from<i>Candida antarctica</i>Produces a Functional Enzyme without Interfacial Activation
  作者：Ylva Wikmark、Karim Engelmark Cassimjee、Richard Lihammar、Jan-E. Bäckvall

  DOI：10.1002/cbic.201500471

  Removal of the mobile region (15 residues) covering the active site of Candida antarctica Lipase A led to a functional enzyme that shows the same stability, activity, and stereoselectivity as the wild‐type enzyme. Interfacial activation, which is a feature of the wild‐type enzyme, was not observed in the truncated variant.

  去除覆盖南极假丝酵母脂肪酶A活性位点的移动区域（15个残基），导致了一种功能性酶，其显示出与野生型酶相同的稳定性，活性和立体选择性。在截短的变体中未观察到界面活化，这是野生型酶的特征。

  日期：2013.2.6

  saturation mutagenesis was applied to solve the latter problem. Mutants with highly improved activity and enantioselectivity relative to wild-type CALB were evolved for the hydrolytic kinetic resolution of p-nitrophenyl 2-phenylpropanoate, with the selectivity factor increasing from E = 1.2 (S) to E = 72 (S) or reverting to E = 42 (R) on an optional basis. Surprisingly, point mutations both in the acyl and alcohol

  南极念珠菌脂肪酶 B (CALB) 是一种强大且易于表达的酶，广泛用于学术和工业实验室，具有多种不同类型的应用。在精细化学品生产中，实例包括外消旋仲醇和胺的酰化动力学拆分以及前手性二醇的去对称化（或反向水解反应）。然而，在酯的水解动力学拆分或酸的酯化动力学拆分（其中手性存在于底物的羧酸部分）的情况下，速率和立体选择性通常较差。在本研究中，基于迭代饱和诱变的定向进化被应用于解决后一个问题。相对于野生型 CALB，具有高度改进的活性和对映选择性的突变体被进化用于对硝基苯基 2-苯基丙酸酯的水解动力学拆分，选择性因子从 E = 1.2 (S) 增加到 E = 72 (S) 或恢复到E = 42 (R) 可选。令人惊讶的是，CALB 的酰基和醇袋中的点突变被证明是必要的。一些进化的 CALB 突变体在其他手性酯的动力学解析中也是有效的生物催化剂，而无需进行新的诱变实验。另一个值得注意的结果涉及发现α-取代羧酸酯的对映互补
