    合成了一系列单取代的脱氧和脱氧氟 2,4-二硝基苯基 (DNP) β-d-吡喃糖苷,并用于探索自发 β-糖苷水解的机制。它们的相对水解速率顺序为 2-脱氧 > 4-脱氧 > 3-脱氧 ≈ 6-脱氧 > 母体 > 6-脱氧-6-氟 > 3-脱氧-3-氟 > 4-脱氧-4-氟 > 2-脱氧-2-氟。6 位、4 位、3 位和 2 位取代糖苷的 pH 无关水解速率与糖环取代基的 σI 值的哈米特相关性是线性的(r = 0.95 至 0.999,ρI = -2.2到-10.7),这与水解速率主要取决于对缺电子过渡态的场效应。正如 Kirkwood-Westheimer 模型预测的那样,DNP 糖苷的相对水解速率可以根据类氧碳鎓离子过渡态的稳定性进行合理化。一系列内水解速率的主要决定因素似乎是环取代基的场效应……

  • Activity of three β-1,4-galactanases on small chromogenic substrates

    beta-1,4-Galactanases belong to glycoside hydrolase family GH 53 and degrade galactan and arabinogalactan side chains of the complex pectin network in plant cell walls. Two fungal beta-1,4-galactanases from Aspergillus aculeatus, Meripileus giganteus and one bacterial enzyme from Bacillus licheniformis have been kinetically characterized using the chromogenic substrate analog 4-nitrophenyl beta-1,4-D-thiogalactobioside synthesized by the thioglycoligase approach. Values of k(cat)/K-m for this substrate with A. aculeatus beta-1,4-galactanase at pH 4.4 and for M. giganteus beta-1,4-galactanase at pH 5.5 are 333 M (1) s (1) and 62 M (1) s (1), respectively. By contrast the B. licheniformis beta-1,4-galactanase did not hydrolyze 4-nitrophenyl beta-1,4-D-thiogalactobioside. The different kinetic behavior observed between the two fungal and the bacterial beta-1,4-galactanases can be ascribed to an especially long loop 8 observed only in the structure of B. licheniformis beta-1,4-galactanase. This loop contains substrate binding subsites -3 and -4, which presumably cause B. licheniformis beta-1,4-galactanase to bind 4-nitrophenyl -1,4-beta-D-thiogalactobioside non-productively. In addition to their cleavage of 4-nitrophenyl -1,4-beta-D-thiogalactobioside, the two fungal enzymes also cleaved the commercially available 2-nitrophenyl-1,4-beta-D-galactopyranoside, but kinetic parameters could not be determined because of transglycosylation at substrate concentrations above 4 mM.
