  Overproduction of CMP-sialic acid synthetase for organic synthesis

  摘要：

  The gene coding for Escherichia coli CMP-sialic acid synthetase (E.C. 2.7.7.43) was cloned and overexpressed in E. coli through a primer-directed polymerase chain reaction. Two plasmids were constructed to produce the native enzyme and a modified enzyme fused with a decapeptide at the C-terminus. The decapeptide tag was used for detection of the enzyme production. Both enzymes produced from E. coli were isolated and purified with an Orange A dye resin and FPLC. Their properties were compared with respect to their kinetic parameters, stability, pH profiles, and substrate specificities. Both enzymes have similar k(cat) and K(m) for NeuAc and CTP but different pH profiles. Contrary to the native enzyme, the modified enzyme is more active at higher pH. Studies on specificity indicate that both enzymes have a high specific activity for C-9 modified NeuAc derivatives at neutral pH. Some C-5 modified (hydroxy, deoxy, and deoxyfluoro) NeuAc derivatives are not acceptable as substrates. The modified enzyme has been used in the synthesis of CMP-NeuAc from ManNAc and CMP and sialyl N-acetyllactosamine (Neu-alpha-2,6Gal-beta-1,4GlcNAc) with in situ generation of NeuAc and regeneration of CMP-NeuAc. The 6-O-acyl derivatives of ManNAc were prepared via transesterification in anhydrous dimethylformamide by using an engineered stable subtilisin variant as a catalyst, and the products were used as substrates in sialic acid aldolase-catalyzed synthesis of 9-O-acyl-NeuAc derivatives.

  保护基游离糖基化：一锅立体控制访问 2-乙酰氨基糖的 1,2-反式糖苷和 (1→6)-连接的二糖

  摘要：

  未受保护的 2-乙酰氨基糖可以在水溶液中使用 2-氯-1,3-二甲基咪唑啉 (DMC) 和合适的碱直接转化为它们的恶唑啉。以醇为溶剂的冷冻干燥和酸催化反应以良好的收率产生相应的1,2-反式-糖苷。或者，在非质子溶剂系统中溶解并在存在过量未保护糖苷作为糖基受体的情况下进行酸性活化，导致立体选择性形成相应的1，2-反式连接的二糖，而无需任何保护基团操作。使用芳基糖苷作为受体的反应是完全区域选择性的，仅产生 (1→6)-连接的二糖。
