    Novel substrates for the measurement of endo-1,4-β-glucanase (endo-cellulase)
    摘要:
    A specific and sensitive substrate for the assay of endo-1,4-beta-glucanase (cellulase) has been prepared. The substrate mixture comprises benzylidene end-blocked 2-chloro-4-nitrophenyl-beta-cellotrioside (BzCNPG3) in the presence of thermostable beta-glucosidase. Hydrolysis by exo-acting enzymes such as beta-glucosidase and exo-beta-glucanase is prevented by the presence of the benzylidene group on the non-reducing end D-glucosyl residue. On hydrolysis by cellulase, the 2-chloro-4-nitrophenyl-beta-glycoside is immediately hydrolysed to 2-chloro-4-nitrophenol and free D-glucose by the b-glucosidase in the substrate mixture. The reaction is terminated and colour developed by the addition of a weak alkaline solution. The assay procedure is simple to use, specific, accurate, robust and readily adapted to automation. This procedure should find widespread applications in biomass enzymology and in the specific assay of endo-1,4-beta-glucanase in general. (C) 2013 Elsevier Ltd. All rights reserved.

    肠杆菌素类似物的简便,多功能化学合成及其在细菌检测中的应用
    摘要:
    铁载体,如Enterobactin(Ent),是可以通过同源转运蛋白与铁一起选择性导入细菌的小分子。因此,铁载体缀合物是用于将功能性试剂递送到细菌中的有前途的策略。在这项工作中,我们提出了一种功能强大的单糖基化肠杆菌素(MGE)易于执行的一锅化学酶法合成方法。当将功能化的MGE与罗丹明荧光团缀合后可提供RhB-Glc-Ent,它可以选择性地标记利用Ent的革兰氏阴性细菌,包括一些大肠杆菌菌株和铜绿假单胞菌。霍乱弧菌利用线性化Ent的细菌,也可以被弱靶向。而且,该靶向在铁限制条件下有效,但在富铁条件下无效。我们的结果表明,RhB‐Glc‐Ent探针不仅对细菌菌株敏感,而且对环境中的铁状况也敏感。

    sole chemical (total yield 10 % in four steps) or enzymatic methods (30 %), our combined chemo‐enzymatic strategy in this article greatly improves the yields of monoglycoside (68 %) and diglycoside (21 %) and decreased the experimental cost (90 %). Furthermore, we tested the water solubility of these glycosides and found that the water solubilities of the two glycosides were 13.1 and 53.7 times of bufalin
    在这项研究中,蟾蜍灵被一种有效的化学酶促策略糖基化。首先,通过化学合成获得2-氯-4-硝基苯基-1-O-β-D-葡萄糖苷(糖供体)。然后,在两种糖基转移酶(Loki 和 ASP)的催化下,合成的糖供体实现了蟾蜍灵的糖基化。最后,两个糖苷,i。例如,bufalin-3-O-β-D-吡喃葡萄糖苷和bufalin-3-O-[β-D-吡喃葡萄糖苷-(1→2)-β-D-吡喃葡萄糖苷)],通过制备型HPLC获得。与我们之前报道的单一化学方法(四步总产率为 10%)或酶法(30%)相比,我们在本文中结合化学酶法的策略大大提高了单糖苷(68%)和双糖苷(21%)的产率和降低了实验成本 (90%)。此外,我们测试了这些苷的水溶性,发现两种苷的水溶性分别是蟾蜍灵的13.1和53.7倍。此外,还评估了这些糖苷对 Na+、K+-ATPase 的抑制活性。单糖基化化合物显示出比蟾蜍灵更强的活性,而二糖基化化合物的活性较低。

    Two chiral binuclear copper(II) complexes were synthesized and characterized for the first time as efficient chemoselective catalysts for the hydrolysis of aryl glycosides and disaccharides in aqueous solution at near neutral pH. Under these conditions, discrimination of epimeric aryl α-glycopyranosides was observed by both 29-fold different reaction rates and 3-fold different proficiency of the catalyst
