  摘要：

  膜结合D-葡萄糖酸-δ-内酯酶（MGL）从Gluconobacter oxydans IFO 3244的膜部分纯化至均一性。在采用1 m CaCl2溶解后，MGL在Ca2+和洗涤剂的存在下得到纯化。SDS-PAGE中出现对应于60 kDa的单一条带。MGL的分子量判断为120k。与细胞质内酯酶不同，MGL在pH 5-5.5的酸性范围内显示出最适pH。它对金属螯合剂如EDTA高度敏感，失去的MGL活性可以通过添加如Ca2+或Mg2+等二价阳离子恢复至原始水平。纯化的MGL严格依赖于Ca2+，并且在即使有洗涤剂存在下，由于Ca2+的缺失而迅速发生变性沉淀。这份交流可能是首次涉及MGL的溶解、纯化和性质的研究。

Simple optimization and reaction engineering allowed us to obtain BDO and 2-KG titers of 18 g L−1 and 42 g L−1, with theoretical yields of >75% and >99%, respectively. One of the promiscuous enzymes identified together with auxiliary promiscuous enzymes was also suitable for stereoconvergent synthesis from a mixture of D-glucose and D-galactose, predominant

  已经提出了由木质纤维素生物质生产化学品的替代品。然而，生物质利用的一个固有挑战是底物的异质性，导致水解后存在混合糖。混合糖的发酵通常导致差的产量和多种副产物的产生，因此使随后的下游加工复杂化。因此，近年来已经开发了系统生物催化来应对这一挑战。在这项工作中，使用基于序列的发现方法，鉴定了几种具有广泛底物混杂的新型酶，这些酶是D-木糖和L转化的合适生物催化剂。-阿拉伯糖，植物生物量中半纤维素的两个主要成分。这些混杂酶使得D-木糖和L-阿拉伯糖能够同时进行生物转化，从而以最大的3 g L -1 h -1的产率和> 95％的产率产生1,4-丁二醇（BDO）。使用O 2作为辅因子循环的辅助底物，该模型系统进一步适应于由戊糖生产α-酮戊二酸（2-KG）的最大生产率，达到4.2 g L -1 h -1和99％的产率。为了验证我们系统的潜在适用性，我们尝试扩大D-木糖和L的BDO和2-KG产量-阿拉伯糖。
• Synthesis of beta-L-2'-deoxy nucleosides

  An improved process for the preparation of 2′-modified nucleosides and 2′-deoxy-nucleosides, such as, β-L-2′-deoxy-thymidine (LdT), is provided. In particular, the improved process is directed to the synthesis of a 2′-deoxynucleoside that may utilize different starting materials but that proceeds via a chloro-sugar intermediate or via a 2,2′-anhydro-1-furanosyl-nucleobase intermediate. Where an 2,2′-anhydro- 1 -furanosyl base intermediate is utilized, a reducing agent, such as Red-Al, and a sequestering agent, such as 15-crown-5 ether, that cause an intramolecular displacement reaction and formation of the desired nucleoside product in good yields are employed. An alternative process of the present invention utilizes a 2,2′-anhydro-1-furanosyl base intermediate without a sequestering agent to afford 2′-deoxynucleosides in good yields. The compounds made according to the present invention may be used as intermediates in the preparation of other nucleoside analogues, or may be used directly as antiviral and/or antineoplastic agents.

  提供了一种改进的2'-改性核苷和2'-脱氧核苷的制备工艺，例如，β-L-2'-脱氧胸苷（LdT）。特别是，改进的工艺针对的是2'-脱氧核苷的合成，该合成可能使用不同的起始材料，但都通过氯糖中间体或通过2,2'-脱水-1-呋喃糖核苷中间体进行。当使用2,2'-脱水-1-呋喃糖碱基中间体时，会采用还原剂（如Red-Al）和隔离剂（如15-冠-5醚），它们能引起分子内位移反应，并形成所需核苷产品的高收率。本发明的一种替代工艺使用2,2'-脱水-1-呋喃糖碱基中间体而不使用隔离剂，也能以高收率获得2'-脱氧核苷。根据本发明制成的化合物可以作为制备其他核苷类似物的中间体，或者可以直接用作抗病毒和/或抗肿瘤剂。

  D-xylonolactone, D-lyxonolactone 2-deoxy-D-ribonolactone toward benzaldehyde and acetone in acidic media, were examined. The reactions involved complex equilibria and were investigated with extensive 13C NMR studies as well as X-ray crystallographic analysis of selected products. Molecular mechanics (MM2) and semiempirical (PM3 and AM1) calculations of some derivatives were carried out in order to facilitate structural
