    Transglycosylation reactions with a crude culture filtrate from Thermoascusaurantiacus
    摘要:
    Some characteristics of regioselectivity and acceptor tolerance in transglycosylation reactions, catalysed by a crude culture filtrate from Thermoascus aurantiacus, were examined by employing methanol and monosaccharides as accepters. When beta-D-mannopyranosyl fluoride was employed as the donor, the anomeric configuration of the newly formed bond was found to depend on the structure of the acceptor used.

  • The determination of complex carbohydrate structure by using carbonyl carbon resonances of peracetylated derivatives

    purported regulation of gene expression in plants (Watkins, 1972; Darvill and Albersheim, 1984). Their physiological roles appear to be influenced by their tertiary and, ultimately, their primary structure (Brisson and Carver, 1983; Homans et al., 1986; Carver, 1984; Montreuil, 1980). Their structural complexity arises from the large number of structurally unique residues present and from the variety

    The conformational flexibility and dynamics of two (16)‐linked disaccharides that are related to the action of the glycosyl transferase GnT‐V have been investigated. NMR NOE and T‐ROE spectroscopy experiments, conformation‐dependent coupling constants and molecular dynamics (MD) simulations were used in the analyses. To facilitate these studies, the compounds were synthesised as α‐d‐[6‐13C]‐Manp‐OMe

    association equilibrium between the FimH lectin and the FimH pilin domain. Moreover, we show that a single N-glycan can bind up to three molecules of FimH, albeit with negative cooperativity, so that a molar excess of accessible N-glycans over FimH on the cell surface favors monovalent FimH binding. Our data provide pivotal insights into the adhesion properties of uropathogenic Escherichia coli strains
    宿主-病原体界面处的多价碳水化合物-凝集素相互作用在感染的建立中起着至关重要的作用。尽管阻止病原体粘附的竞争性拮抗剂是有前途的抗菌药物,但这些复杂粘附过程的分子机制仍然知之甚少。在这里,我们表征了来自尿路致病性大肠杆菌菌株的菌毛粘附素 FimH 与其在尿路上皮糖蛋白上的天然高甘露糖型 N-聚糖结合表位之间的相互作用。晶体结构和配体结合和解离的详细动力学表征表明,FimH 的结合口袋进化为能够识别末端 α(1-2)-、α(1-3)- 和 α(1-6)具有相似亲和力的天然高甘露糖型 N-聚糖的连接甘露糖苷。我们证明了 FimH 的结构域分离状态与其结构域相关状态相比的 2000 倍高亲和力是配体独立的,并且与热力学循环一致,其中配体结合改变了 FimH 凝集素和 FimH 之间的结合平衡皮林域。此外,我们表明单个 N-聚糖可以结合最多三个 FimH 分子,尽管具有负协同性,因此细胞表面上比 FimH
  • A simple strategy for changing the regioselectivity of glycosidase-catalysed formation of disaccharides
    作者:Kurt G.I. Nilsson
    DOI:10.1016/0008-6215(87)80271-9
    日期:1987.9
    The regioselectivity of glycosidase-catalysed formation of disaccharides can be changed by using alpha- or beta-glycosyl acceptors with various aglycons. The preponderant formation of other than (1----6) linkages can be effected with glycosidases which normally give (1----6) linkages. Thus, an alpha-D-galactosidase can be induced to catalyse the formation mainly of alpha-(1----2)-, alpha-(1----3),
    通过使用带有各种糖苷配基的α-或β-糖基受体可以改变糖苷酶催化的二糖形成的区域选择性。除了(1 ---- 6)键以外,优势糖的形成可以通过通常具有(1 ---- 6)键的糖苷酶来实现。因此,可以诱导α-D-半乳糖苷酶主要催化α-(1 ---- 2)-,α-(1 ---- 3)或α-(1 ---- 6)的形成。 )连接的半乳​​糖苷。糖苷配基的结构和糖苷键的构型均可对二糖形成的区域选择性产生显着影响。描述了α-D-Galp-(1 ---- 3)-α-D-Galp-OMe,β-D-Galp-(1 ---- 3)的酶促合成,产率为20-30% β-D-Galp-OMe,β-D-Galp-(1 ---- 6)-α-D-Galp-OMe,α-D-Manp-(1 ---- 2)-alpha- D-Manp-OMe,alpha-D-Manp-(1 ---- 6)-alpha-D-Manp-OMe,alpha-D-Galp-(1

    mass spectrometry (ERMS), and 1H nuclear magnetic resonance spectroscopy. The CID experiments of sodiated species of disaccharides and ERMS experiments revealed that the order of stability of mannosyl linkages was as follows: 6-linked > 4-linked ≧ 2-linked > 3-linked mannosyl residues. Analysis of linear trisaccharides revealed that the order observed in disaccharides could be applied to higher glycans
    使用碰撞诱导解离(CID),能量分辨质谱(ERMS)和1制备了一系列与由α-甘露糖苷组成的与天然存在的和生物学上相关的聚糖相关的化合物H核磁共振波谱学。二糖的糖化物种类的CID实验和ERMS实验显示,甘露糖基键的稳定性的顺序如下:6-连接的> 4-连接的≥2-连接的> 3-连接的甘露糖基残基。线性三糖的分析表明,在二糖中观察到的顺序可以应用于更高的聚糖。支链的三糖显示出明显的解离模式,具有两个构成的二糖离子。使用二糖光谱可以估算该离子混合物的含量。支链三糖中3-位和6-位甘露糖键的解显示3-键的断裂速度是6-键的两倍。观察到溶液相解和气相解离具有相似的能量。
