  Optimized synthesis of novel prenyl ferulate performed by feruloyl esterases from Myceliophthora thermophila in microemulsions

  摘要：

  Five feruloyl esterases (FAEs; EC 3.1.1.73), FaeA1, FaeA2, FaeB1, and FaeB2 from Myceliophthora thermophila C1 and MtFae1a from M. thermophila ATCC 42464, were tested for their ability to catalyze the transesterification of vinyl ferulate (VFA) with prenol in detergentless microemulsions. Reaction conditions were optimized investigating parameters such as the medium composition, the substrate concentration, the enzyme load, the pH, the temperature, and agitation. FaeB2 offered the highest transesterification yield (71.5 +/- 0.2%) after 24 h of incubation at 30 A degrees C using 60 mM VFA, 1 M prenol, and 0.02 mg FAE/mL in a mixture comprising of 53.4:43.4:3.2 v/v/v n-hexane:t-butanol:100 mM MOPS-NaOH, pH 6.0. At these conditions, the competitive side hydrolysis of VFA was 4.7-fold minimized. The ability of prenyl ferulate (PFA) and its corresponding ferulic acid (FA) to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals was significant and similar (IC50 423.39 mu M for PFA, 329.9 mu M for FA). PFA was not cytotoxic at 0.8-100 mu M (IC50 220.23 mu M) and reduced intracellular reactive oxygen species (ROS) in human skin fibroblasts at concentrations ranging between 4 and 20 mu M as determined with the dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay.

  脂酶介导的酚酸乙烯基酯及其类似物对甲基α-d-吡喃葡萄糖苷的酰化反应中的供体特异性和区域选择性

  摘要：

  使用固定化的脂酶将几种模型酚和非酚乙烯基酯酰化作为模型受体的甲基α- d-吡喃葡萄糖苷。研究了供体特异性和反应的区域选择性。结构上不同的供体的转化率和酰化速率表明，Lipolase的合成反应性对应于A型阿魏酸酯酶的水解活性。Lipolase对甲基α- d-吡喃葡萄糖苷的主要位置表现出显着的区域选择性。当酚酸的乙烯基酯（羟基苯甲酸酯，羟基苯基链烷酸酯和羟基肉桂酸酯）用作酰基供体时，酰化作用仅发生在6- O主位置。除了主要的6- O-酰基产品（52–79％）外，2,6-二-使用非酚供体时，从反应混合物中分离出O-酰化衍生物（2-13％）（酚酸的完全甲氧基化衍生物的乙烯基酯，以及苯甲酸乙烯酯，肉桂酸酯或某些杂环类似物）。

• Glycerol acyl-transfer kinetics of a circular permutated Candida antarctica lipase B

  Triacylglycerols containing a high abundance of unusual fatty acids, such as gamma-linolenic acid, or novel arylaliphatic acids, such as ferulic acid, are useful in pharmaceutical and cosmeceutical applications. Candida antarctica lipase B (CALB) is quite often used for non-aqueous synthesis, although the wildtype enzyme can be rather slow with bulky and sterically hindered acyl donor substrates. The catalytic performance of a circularly permutated variant of CALB, cp283, with various acyl donors and glycerol was examined. In comparison to wild-type CALB, butyl oleate and ethyl gamma-linolenate glycerolysis rates were 2.2- and 4.0-fold greater, respectively. Cp283 showed substrate inhibition by glycerol, which was not the case with the wild-type version. With either ethyl ferulate or vinyl ferulate acyl donors, cp283 matched the performance of wild-type CALB. Changes in active site accessibility resulting from circular permutation led to increased catalytic rates for bulky fatty acid esters but did not overcome the steric hindrance or energetic limitations experienced by arylaliphatic esters.
