  • Congruent Strategies for Carbohydrate Sequencing. 1. Mining Structural Details by MS<i><sup>n</sup></i>

    Excessive fragmentation is the property of small oligomers where collisional energy within a smaller number of oscillators dissipates through extensive fragmentation. The procedures discussed in this report are unified into a singular strategy using an ion trap mass spectrometer with the sensitivity expected for electron multiplier detection. Although a small set of structures have been discussed, the
    该报告是三份系列报告中的第一份,主要针对建立一致的碳水化合物测序策略。这些报告分为(i)通过MSn分解解释小低聚物结构所有方面的分析考虑因素;(ii)使用离子片段库和相关工具进行高通量分析的数据库支持;以及(iii)用于分析的结论算法。从MSn拆卸途径定义寡糖拓扑结构。这份第一份报告的分析性贡献探索了通过离子阱质谱法暴露的结构细节的局限性,其中样品制备为甲基衍生物,并作为属离子加合物进行了分析。这项数据挖掘工作着眼于将小寡聚物的片段与立体特异性聚糖结构相关联,结果归因于属离子加合和分析物构象的结合。容易的糖苷裂解引入了一个不稳定性点(喃糖基-1-烯),该点在碰撞激活后会引发随后的环断裂。产物质量和离子强度随残基间键合,支化位置和单体立体化学而变化。过度碎片化是小型低聚物的特性,少数振荡器中的碰撞能量会通过大量碎片化消散。使用离子阱质谱仪将本报告中讨论的程序统一为单一策略,其灵敏度可预

  • Highly Efficient Chemoenzymatic Synthesis of α-Galactosyl Epitopes with a Recombinant α(1→3)-Galactosyltransferase
    作者:Jianwen Fang、Jun Li、Xi Chen、Yingnan Zhang、Jianqiang Wang、Zhengmao Guo、Wei Zhang、Libing Yu、Keith Brew、Peng George Wang

    alpha-Galactosyl epitopes are carbohydrate structures bearing a Gal alpha 1-3Gal beta terminus. The interaction of these epitopes on the surface of animal cells with anti-alpha-galactosyl antibodies in human serum is believed to be the main cause in antibody-mediated hyperacute rejection in xenotransplantation. This report describes an efficient chemoenzymatic approach based on the use of recombinant alpha(1 --> 3)-galactosyltransferase (alpha 1,3-GalT) for the synthesis of xenoactive alpha-galactosyl epitopes, which are highly desired in the research of xenotransplantation and immunotherapy. A truncated bovine alpha 1,3-GalT (80-368) was cloned into the pET15b vector-and Subsequently transformed into E. coli BL21 strain. This expression system efficiently produced the soluble recombinant enzyme on a large scale with highly specific activity. A variety of alpha(1 --> 3)galactosylated epitopes were synthesized using such a recombinant enzyme. In a unique fashion, alpha-galactosyl pentasaccharide was synthesized via a one-pot, two-step enzymatic synthesis with in situ cofactor regeneration.
