  Stereoselective synthesis of 1-O-β-feruloyl and 1-O-β-sinapoyl glucopyranoses

  摘要：

  1-O-beta-Feruloyl and 1-O-beta-sinapoyl glucopyranoses are two common substrates for serine carboxypeptidase-like acyltransferases and serve as acyl donors in the biosynthesis of numerous secondary metabolites. In addition, they are involved in plant cell wall cross-linking and are also ideal substrates for studying the kinetics of lignification involving hydroxycinnamates. We report the first chemical (and multi-gram scale) synthesis of 1-O-beta-feruloyl and 1-O-beta-sinapoyl glucopyranoses. (C) 2011 Elsevier Ltd. All rights reserved.

  L241D/W243N. In order to guide a more general use of Os9BGlu31 variants as transglycosylation catalysts, we built cheminformatics models based on topological descriptors of the substrates. These models showed useful predictive potential on the external validation set and are allowing the identification of efficient catalytic routes to novel phytohormone and antibiotic glucoconjugates of interest.

  转糖苷酶是具有催化从生物质衍生的原料开始的各种高价值化合物合成的酶。改善其活性并拓宽底物范围是使该生物催化剂家族广泛应用的重要目标。在这项工作中，我们设计了20个水稻转糖苷酶Os9BGlu31突变体，并评估了它们在18种不同底物上的462次反应中的催化作用。这使我们能够鉴定出扩大了其底物范围并显示出高活性的突变体，包括W243L和W243N。我们还开发了双重突变体，例如L241D / W243N，它们在某些底物上具有很高的活性，并且对水解具有特殊的特异性。为了指导Os9BGlu31变体更普遍地用作转糖基化催化剂，我们基于底物的拓扑描述符建立了化学信息学模型。这些模型在外部验证集上显示出有用的预测潜力，并且允许鉴定出有效的催化途径，以催化新型目标植物激素和抗生素葡萄糖缀合物。

  UDP-glucose:gallic acid glucosyltransferase activity. UGT84A13 was functionally expressed in Escherichia coli as N-terminal His-tagged protein. In vitro kinetic measurements with the purified recombinant enzyme revealed a clear preference for hydroxybenzoic acids as glucosyl acceptor in comparison to hydroxycinnamic acids. Of the preferred in vitro substrates, protocatechuic, vanillic and gallic acid, only

  编码形成酯的羟基苯甲酸葡萄糖基转移酶 UGT84A13 的 cDNA 是从 Quercus robur 膨胀芽和幼叶的 cDNA 文库中分离出来的。该酶与来自葡萄属的白藜芦醇/羟基肉桂酸酯和羟基苯甲酸酯/羟基肉桂酸酯葡萄糖基转移酶显示出高度的序列同一性，并聚集在植物葡萄糖基转移酶的系统发育组 L 中，主要参与 1-O-β-D-葡萄糖酯的形成。计算机转录组分析证实了 UGT84A13 在 Quercus 组织中的表达，该组织之前显示出 UDP-葡萄糖：没食子酸葡萄糖基转移酶活性。UGT84A13 在大肠杆菌中作为 N 端 His 标记蛋白在功能上表达。用纯化的重组酶进行的体外动力学测量显示，与羟基肉桂酸相比，羟基苯甲酸明显更倾向于作为葡萄糖基受体。在优选的体外底物原儿茶酸、香草酸和没食子酸中，只有后者及其相应的 1-O-β-D-葡萄糖酯被发现在年轻的橡树叶中积累。这表明在植物中 UGT84A13
• Enzymology of udp-glucose:sinapic acid glucosyltransferase from brassica napus
  作者：Shawn X. Wang、Brian E. Ellis

  日期：1998.9

  UDP-glucose:sinapic acid glucosyltransferase (SGT; EC 2.4.1.120) was purified from 60-h-old seedlings of Brassica napus. The purified SGT appears to be a cytosolic monomeric polypeptide with a M-r of 42 kDa and a pI of 5. Kinetic analysis suggested that the catalytic mechanism used by SGT best fits a "random bi-bi" model, with a K m(UDP-glucose) of 2.4 mM and K-m(sinapic acid) of 0.16 mM. SGT also catalyzes the reverse reaction in vitro, using UDP and sinapoylglucose to form UDP-glucose. No cofactors are required for enzyme activity, but reducing agents and glycerol are required to stabilize the activity. The enzyme is strongly inhibited by p-OH-mercuribenzoic acid, UDP, TDP, Zn++, Cu++ and Hg++. (C) 1998 Elsevier Science Ltd. All rights reserved.
