    Oxidation and metal-ion affinities of a novel cyclic tetrasaccharide
    摘要:
    The cyclic tetrasaccharide, cyclo-{--> 6)-alpha-D-Glcp-(1 --> 3)-alpha-D-Glcp-(1 --> 6)-alpha-D-Glcp-(1 --> 3)-alpha-D-Glcp-(1 -->}, was oxidized in high yield to a dicarboxylic acid, cyclo-{--> 6)-alpha-D-Glcp-(1 --> 3)-alpha-D-GIcpA-(1 --> 6)-alpha-D-Glcp-(1 --> 3)-alpha-D-Glcp A-(1 -->}. The parent and oxidized compound were then screened for the ability to form stable complexes with 20 metal cations. Ion-exchange thin-layer chromatography was utilized to survey binding in aqueous and 50% methanolic solutions. The screening identified Pb2+, Fe2+ and Fe3+ as forming strong metal chelates with the oxidized cyclic tetrasaccharide. The stoichiometry of the oxidized cyclic tetrasaccharide and Pb2+ complex was determined to be 1:1 using aqueous gel-permeation chromatography. Perturbations between the free and complexed structure were examined using NMR spectroscopy. Molecular simulations were used to identify a probable structure of oxidized cyclic tetrasaccharide complexed with Pb2+. Published by Elsevier Ltd.

    Purification and Characterization of Glucosyltransferase and Glucanotransferase Involved in the Production of Cyclic Tetrasaccharide inBacillus globisporusC11
    摘要:
    从球形芽孢杆菌(Bacillus globisporus C11)中纯化了参与从α-1,4-葡聚糖生产环状四糖(CTS;cyclo {→6}-α-D-glucopyranosyl-(1→3)-α-D-glucopyranosyl-(1→6)-α-D-glucopyranosyl-(1→3)-α-D-glucopyranosyl- (1→))的葡萄糖基转移酶和葡聚糖转移酶。前者是一种 1,6-α-葡糖基转移酶(6GT),可催化麦芽寡糖(MOS)非还原端一个葡糖基残基的α-1,6-反式葡糖基化,从而从 MOS 生成α-异麦芽糖基-MOS。后者是一种异麦芽糖基转移酶(IMT),可催化异麦芽糖基残基的α-1,3-、α-1,4-和α,β-1,1-分子间转糖基化。当 IMT 催化 α-1,3-转糖基化时,α-异麦芽糖基-(1→3)-α-异麦芽糖基-MOS 由 α-异麦芽糖基-MOS 生成。此外,IMT催化环化,通过分子内转糖基化作用,从α-异麦芽糖基-(1→3)-α-异麦芽糖基-MOS生成 CTS。因此,这两种酶从 MOS 合成 CTS 的机制似乎遵循三个步骤:1)MOS→α-异麦芽糖基-MOS(6GT);2)α-异麦芽糖基-MOS→α-异麦芽糖基-(1→3)-α-异麦芽糖基-MOS(IMT);3)α-异麦芽糖基-(1→3)-α-异麦芽糖基-MOS→CTS +MOS(IMT)。经 SDS-PAGE 测定,6GT 的分子量为 137 kDa。6GT 的最适 pH 值和温度分别为 pH 6.0 和 45°C。6GT 被各种二价阳离子强烈激活和稳定。经 SDS-PAGE 鉴定,IMT 的分子量为 102 kDa。IMT 的最适 pH 值和温度分别为 pH 6.0 和 50°C。这种酶在 pH 值为 4.5 至 9.0 以及加热至 40°C 60 分钟时都很稳定。二价阳离子对这种酶的稳定性和活性没有影响。

    The glucosyl transfer reaction of kojibiose phosphorylase (KPase) from Thermoanaerobacter brockii ATCC35047 was examined using cyclo--->6)-alpha-d-Glcp-(1-->3)-alpha-d-Glcp-(1-->6)-alpha-d-Glcp-(1-->3)-alpha -d-Glcp-(1-->} (CTS) as an acceptor. KPase produced four transfer products, saccharides 1-4. The structure of a major product, saccharide 4, was 2-O-alpha-d-glucopyranosyl-CTS, cyclo--->6)-a
    使用cyclo--> 6)-alpha-d-Glcp-(1-> 3)-alpha-d-Glcp-(1-- > 6)-α-d-Glcp-(1-> 3)-α-d-Glcp-(1->}(CTS)作为受体,KPase产生了四个转移产物,即糖类1-4。一种主要产物糖4是2-O-α-d-葡萄糖基-CTS,环--> 6)-alpha-d-Glcp-(1-> 3)-alpha-d-Glcp- (1-> 6)-[alpha-d-Glcp-(1-> 2)]-alp ha-d-Glcp-(1-> 3)-alpha-d-Glcp-(1-> }。其他转移产物糖1-3,分别是2-O-α-曲二生物基-,2-O-α-曲三糖基和2-O-α-曲四糖基-CTS,这些结果表明KPase已转移在CTS的环葡萄糖残基的C-2位置有一个葡萄糖残基。该酶还催化了2-O-α-d-甘露聚糖基-CTS的侧链的扩链反应。

    Abstract Alternanase catalyzes the hydrolysis of alternan, an α-(1→3)-α-(1→6)- d -glucan produced by Leuconostoc mesenteroides, resulting in the formation of a cyclic tetramer cyclo→3)-α- d -Glcp-(1→6)-α- d -Glcp-(1→}2 (cGlc4).

    gave mannose-CI8 conjugates with a variety of average mannose incorporation numbers (2-7). The average numbers were deduced from MALDI-TOF mass and (1)H NMR spectroscopy. The binding ability of mannose-CI8 conjugates to concanavalin A increased with the increasing numbers of average mannose incorporation, reaching a plateau at tetravalence, as estimated from a latex bead-based agglutination lectin assay
    对凝集素具有高亲和力的小糖簇的合成是糖技术中的重要课题之一。尽管环状α-(1→6)-d-八葡糖苷(Cl8)是一个有吸引力的支架,上面放置了糖基侧基,但该化合物仅具有仲羟基,该仲羟基对取代反应相对没有反应。CI8邻位二醇的氧化和2-氨基乙基甘露糖苷对所得二醛的还原胺化反应得到具有各种平均甘露糖掺入数(2-7)的甘露糖-CI8共轭物。从MALDI-TOF质量和(1)1 H NMR光谱推断出平均值。甘露糖-CI8缀合物对伴刀豆球蛋白A的结合能力随平均甘露糖掺入次数的增加而增加,在四价时达到平稳状态,如基于乳胶珠的凝集凝集素测定所估计的。毒性试验证明了甘露糖-CI8缀合物的生物相容性。
