exploitation of its substrate specificity and synthetic utility. Several potential acceptor substrates were synthesized in this study, including mono- and oligosaccharides, glycolipids, and glycopeptides and their sulfate derivatives. Some CMP-sialic acid derivatives with modification at the C-5 position were also prepared for evaluation as donor substrates. It was found that the enzyme exhibits a broader
来自淋病奈瑟菌的 α-2,3-唾液酸转移酶在大肠杆菌中过度生产,以利用其底物特异性和合成效用。本研究合成了几种潜在的受体底物,包括单糖和寡糖、糖脂、糖肽及其硫酸盐衍生物。还制备了一些在 C-5 位进行修饰的 CMP-唾液酸衍生物作为供体底物进行评估。发现与其他唾液酸转移酶相比,该酶表现出更广泛的受体底物特异性,尽管供体特异性非常有限。已证明该酶在代表性唾液酸糖缀合物的制备性合成中的应用。在这项工作和其他人的工作的基础上,
