    Chemoenzymatic synthesis of thio-nod factor intermediates — Enzymatic transfer of glucosamine on thiochitobiose derivatives
    摘要:
    本研究报道了用化学酶法合成结瘤因子硫代类似物的过程,在这些类似物中,非还原端葡糖胺残基可用于在游离 NH2 基上引入脂肪酸分子。我们介绍了 UDP-GlcNH2 的化学合成及其在牛半乳糖基转移酶(EC 2.4.1.90)将 GlcNH2 酶促转移到壳寡糖、硫代壳寡糖和烯丙基硫代壳寡糖的非还原端 N-乙酰葡糖胺残基的 O-4 上的应用。利用 TLC 和 MALDI MS 对壳寡糖和硫代壳寡糖的酶促反应进行了跟踪,结果表明这些二糖约有 50% 转化为所需产物。然而,这些还原性三糖不能完全不含盐分,并在离子交换色谱中降解。因此,我们研究了非还原性烯丙基硫代几丁质类似物的酶促转移。我们在此描述了这种硫代二糖的化学合成及其非还原端氨基葡萄糖残基 O-4 上 GlcNH2 的酶促转移,从而得到所需的烯丙基硫代三糖。这种硫代异糖的纯度为 41%,并通过 1H NMR (HSQC) 和 HRMS 进行了表征。

    6-Chloropurine and 2,6-dichloropurine were regioselectively glycosylated at position 7 to give the corresponding peracetylated N7-nucleosides, which can be suitable for other purine transformations. In this work, we study the distribution of N7/N9-isomers produced via the Vorbrüggen method under different conditions, using an N-trimethylsilylated purine derivative and SnCl4 or TiCl4 as a catalyst.

  • The crystal structure of an inverting glycoside hydrolase family 9 exo-β-<scp>D</scp>-glucosaminidase and the design of glycosynthase
    作者:Yuji Honda、Sachiko Arai、Kentaro Suzuki、Motomitsu Kitaoka、Shinya Fushinobu

    Exo-β-D-glucosaminidase (EC 3.2.1.165) from Photobacterium profundum (PpGlcNase) is an inverting GH (glycoside hydrolase) belonging to family 9. We have determined the three-dimensional structure of PpGlcNase to describe the first structure–function relationship of an exo-type GH9 glycosidase. PpGlcNase has a narrow and straight active-site pocket, in contrast with the long glycan-binding cleft of a GH9 endoglucanase. This is because PpGlcNase has a long loop, which blocks the position corresponding to subsites −4 to −2 of the endoglucanase. The pocket shape of PpGlcNase explains its substrate preference for a β1,4-linkage at the non-reducing terminus. Asp139, Asp143 and Glu555 in the active site were located near the β-O1 hydroxy group of GlcN (D-glucosamine), with Asp139 and Asp143 holding a nucleophilic water molecule for hydrolysis. The D139A, D143A and E555A mutants significantly decreased hydrolytic activity, indicating their essential role. Of these mutants, D139A exclusively exhibited glycosynthase activity using α-GlcN-F (α-D-glucosaminyl fluoride) and GlcN as substrates, to produce (GlcN)2. Using saturation mutagenesis at Asp139, we obtained D139E as the best glycosynthase. Compared with the wild-type, the hydrolytic activity of D139E was significantly suppressed (&lt;0.1%), and the F−-release activity also decreased (&lt;3%). Therefore the glycosynthase activity of D139E was lower than that of glycosynthases created previously from other inverting GHs. Mutation at the nucleophilic water holder is a general strategy for creating an effective glycosynthase from inverting GHs. However, for GH9, where two acidic residues seem to share the catalytic base role, mutation of Asp139 might inevitably reduce F−-release activity.

    深色光杆菌(Photobacterium profundum)的外β-D-葡糖苷酶(EC 3.2.1.165)(PpGlcNase)是一种属于第 9 家族的倒置型 GH(糖苷水解酶)。我们测定了 PpGlcNase 的三维结构,首次描述了外型 GH9 糖苷酶的结构-功能关系。PpGlcNase 有一个狭窄而笔直的活性位点口袋,与 GH9 内聚糖酶的长聚糖结合裂隙形成鲜明对比。这是因为 PpGlcNase 有一个长环,挡住了与内切葡聚糖酶的-4 至-2 子位点相对应的位置。PpGlcNase 的口袋形状解释了它对非还原末端的 β1,4-连接底物的偏好。活性位点中的 Asp139、Asp143 和 Glu555 位于 GlcN(D-氨基葡萄糖)的 β-O1 羟基附近,其中 Asp139 和 Asp143 有一个亲核水分子用于水解。D139A、D143A 和 E555A 突变体大大降低了水解活性,表明它们起着至关重要的作用。在这些突变体中,D139A 只表现出以 α-GlcN-F(α-D-葡萄糖氨酰氟)和 GlcN 为底物生成 (GlcN)2 的糖合成酶活性。通过对 Asp139 进行饱和突变,我们获得了 D139E 作为最佳糖合成酶。与野生型相比,D139E的水解活性明显受到抑制(0.1%),F--释放活性也有所下降(3%)。因此,D139E 的糖合成酶活性低于之前由其他倒置 GHs 生成的糖合成酶。在亲核水座上发生突变是利用倒置 GHs 制造有效糖合成酶的一般策略。然而,对于 GH9 来说,两个酸性残基似乎共同起着催化碱基的作用,因此 Asp139 的突变可能会不可避免地降低 F 释放活性。
