    摘要:
    我们报告了蔗糖基受体和糖基氟供体之间的合成糖基化反应,产生衍生的三糖。该反应在室温下在水性溶剂混合物中进行。钙盐和叔胺碱促进反应,对呋喃果糖苷单元的 3'-位或 1'-位具有高位点选择性。由于非酶水性寡糖合成尚不成熟,因此进行了机理研究,以确定选择性的起源,我们假设这与蔗糖中羟基阵列的结构有关。各种单脱氧蔗糖类似物的溶液构象揭示了羟基在同时介导这种水性糖基键形成反应和位点选择性方面的协同性质。

  • Gluco-oligomers initially formed by the reuteransucrase enzyme of Lactobacillus reuteri 121 incubated with sucrose and malto-oligosaccharides
    作者:Justyna M Dobruchowska、Xiangfeng Meng、Hans Leemhuis、Gerrit J Gerwig、Lubbert Dijkhuizen、Johannis P Kamerling
    DOI:10.1093/glycob/cwt048
    日期:2013.9
    The probiotic bacterium Lactobacillus reuteri 121 produces a complex, branched (1 → 4, 1 → 6)-α-d-glucan as extracellular polysaccharide (reuteran) from sucrose (Suc), using a single glucansucrase/glucosyltransferase (GTFA) enzyme (reuteransucrase). To gain insight into the reaction/product specificity of the GTFA enzyme and the mechanism of reuteran formation, incubations with Suc and/or a series of malto-oligosaccharides (MOSs) (degree of polymerization (DP2–DP6)) were followed in time. The structures of the initially formed products, isolated via high-performance anion-exchange chromatography, were analyzed by matrix-assisted laser-desorption ionization time-of-flight mass spectrometry and 1D/2D 1H/13C NMR spectroscopy. Incubations with Suc only, acting as both donor and acceptor, resulted in elongation of Suc with glucose (Glc) units via alternating (α1 → 4) and (α1 → 6) linkages, yielding linear gluco-oligosaccharides up to at least DP ∼ 12. Simultaneously with the ensemble of oligosaccharides, polymeric material was formed early on, suggesting that alternan fragments longer than DP ∼ 12 have higher affinity with the GTFA enzyme and are quickly extended, yielding high-molecular-mass branched reuteran (4 × 107 Da). MOSs (DP2–DP6) in the absence of Suc turned out to be poor substrates. Incubations of GTFA with Suc plus MOSs as substrates resulted in preferential elongation of MOSs (acceptors) with Glc units from Suc (donor). This apparently reflects the higher affinity of GTFA for MOSs compared with Suc. In accordance with the GTFA specificity, most prominent products were oligosaccharides with an (α1 → 4)/(α1 → 6) alternating structure.
    益生菌吕特氏乳杆菌(Lactobacillus reuteri)121利用一种单一的葡聚糖琥珀酸酶/葡糖基转移酶(GTFA)(reuteransucrase),从蔗糖(Suc)中产生一种复杂的支链(1→4,1→6)-α-d-葡聚糖作为胞外多糖(reuteran)。为了深入了解 GTFA 酶的反应/产物特异性和芦丁聚糖的形成机制,对 Suc 和/或一系列麦芽寡糖(MOS)(聚合度为 DP2-DP6)的孵育过程进行了及时跟踪。最初形成的产物通过高效阴离子交换色谱法分离出来,并通过基质辅助激光解吸电离飞行时间质谱法和 1D/2D 1H/13C NMR 光谱法分析其结构。在同时作为供体和受体的 Suc 诱导下,Suc 通过交替 (α1 → 4) 和 (α1 → 6) 连接与葡萄糖(Glc)单元发生伸长,产生线性葡萄糖寡糖,至少达到 DP ∼ 12。在低聚糖集合的同时,很早就形成了聚合物质,这表明长于 DP ∼ 12 的交替聚糖片段与 GTFA 酶的亲和力较高,并能迅速延伸,产生高分子质量的支链芦丁聚糖(4 × 107 Da)。在没有 Suc 的情况下,MOSs(DP2-DP6)是较差的底物。将 GTFA 与作为底物的 Suc 和 MOS 一起培养,结果是 MOS(接受者)优先与来自 Suc(供体)的 Glc 单位发生延伸。这显然反映出与 Suc 相比,GTFA 对 MOS 的亲和力更高。根据 GTFA 的特异性,最主要的产物是具有(α1 → 4)/(α1 → 6)交替结构的寡糖。
