  •  -D-Galactosidase from Paenibacillus thiaminolyticus catalyzing transfucosylation reactions
    作者:E. Benesova、P. Lipovova、H. Dvorakova、B. Kralova
    DOI:10.1093/glycob/cwp196
    日期:2010.4.1
    A genomic library of bacterial strain Paenibacillus thiaminolyticus was constructed and the plasmid DNA of the clone, containing the gene encoding β-d-galactosidase with β-d-fucosidase activity, detected by 5-bromo-4-chloro-3-indoxyl β-d-galactopyranoside, was sequenced. Cells of Escherichia coli BL21 (DE3) were used for production of the enzyme in the form of a histidine-tagged protein. This recombinant fusion protein was purified using Ni-NTA agarose affinity chromatography and characterized by using p-nitrophenyl β-d-fucopyranoside (Km value of (1.18 ± 0.06) mmol/L), p-nitrophenyl β-d-galactopyranoside (Km value of (250 ± 40) mmol/L), p-nitrophenyl β-d-glucopyranoside (Km value of (77 ± 6) mmol/L), and lactose (Km value of (206 ± 5) mmol/L) as substrates. Optimal pH and temperature were estimated as 5.5 and 65°C, respectively. According to the amino acid sequence, the molecular weight of the fusion protein was calculated to be 68.6 kDa and gel filtration chromatography confirmed the presence of the enzyme in a monomeric form. In the following step, its ability to catalyze transfucosylation reactions was tested. The enzyme was able to catalyze the transfer of fucosyl moiety to different p-nitrophenyl glycopyranosides (producing p-nitrophenyl β-d-fucopyranosyl-(1,3)-β-d-fucopyranoside, p-nitrophenyl β-d-fucopyranosyl-(1,3)-α-d-glucopyranoside, p-nitrophenyl β-d-fucopyranosyl-(1,3)-α-d-mannopyranoside, and p-nitrophenyl β-d-fucopyranosyl-(1,6)-α-d-galactopyranoside) and alcohols (producing methyl β-d-fucopyranoside, ethyl β-d-fucopyranoside, 1-propyl β-d-fucopyranoside, 2-propyl β-d-fucopyranoside, 1-octyl β-d-fucopyranoside, and 2-octyl β-d-fucopyranoside). These results indicate the possibility of utilizing this enzyme as a promising tool for enzymatic synthesis of β-d-fucosylated molecules.
    构建了细菌株Paenibacillus thiaminolyticus的基因组文库,并对克隆中包含编码具有β-d-岩藻糖苷酶活性的β-d-半乳糖苷酶基因的质粒DNA进行了测序。采用大肠杆菌BL21(DE3)细胞生产该酶,形式为带有组氨酸标签的蛋白质。使用Ni-NTA琼脂糖亲和层析纯化了该重组融合蛋白,并通过使用对硝基苯基β-d-岩藻糖吡喃苷(Km值为(1.18 ± 0.06) mmol/L)、对硝基苯基β-d-半乳糖吡喃苷(Km值为(250 ± 40) mmol/L)、对硝基苯基β-d-葡萄糖吡喃苷(Km值为(77 ± 6) mmol/L)和乳糖(Km值为(206 ± 5) mmol/L)作为底物进行特征分析。最佳pH和温度分别估计为5.5和65°C。根据氨基酸序列计算,该融合蛋白的分子量为68.6 kDa,凝胶过滤层析确认该酶以单体形式存在。在接下来的步骤中,测试其催化转岩藻糖化反应的能力。该酶能够催化将岩藻糖基转移到不同的对硝基苯基糖吡喃苷上(生成对硝基苯基β-d-岩藻糖苷-(1,3)-β-d-岩藻糖苷、对硝基苯基β-d-岩藻糖苷-(1,3)-α-d-葡萄糖苷、对硝基苯基β-d-岩藻糖苷-(1,3)-α-d-甘露糖苷和对硝基苯基β-d-岩藻糖苷-(1,6)-α-d-半乳糖苷)和醇类(生成甲基β-d-岩藻糖苷、乙基β-d-岩藻糖苷、1-丙基β-d-岩藻糖苷、2-丙基β-d-岩藻糖苷、1-辛基β-d-岩藻糖苷和2-辛基β-d-岩藻糖苷)。这些结果表明使用该酶作为酶促合成β-d-岩藻糖化分子的有希望工具的可能性。

    basis of the specific recognition of galactose or sialic acid by a receptor, a series of CORMs based on carbohydrates were synthesized and evaluated. The test results show that all the complexes displayed anticancer activity. Among them, the effects of the complexes of galactose (1), GalNAc (8) and sialic acid (10) were very distinct. Complex 1 displayed higher activity against HeLa, HePG2, MCF-7 and HT-29
    含钴的释放CO的分子(CORM)具有许多生物活性,但大多数不溶于水,并且对组织和器官没有选择性。基于受体对半乳糖或唾液酸的特异性识别,合成和评估了一系列基于碳水化合物的CORM。测试结果表明,所有复合物均显示出抗癌活性。其中,半乳糖(1),GalNAc(8)和唾液酸(10)的复合物的作用非常明显。复合物1对HeLa,HePG2,MCF-7和HT-29细胞的增殖表现出比顺式更高的活性铂(DDP),其选择性远比正常细胞W138好于DDP。此外,复合物的摄取1,8和10通过的HePG2 HT-29,A549和RAW264.7细胞系进行了研究。复合物1的各细胞系的摄取率不同,这4种细胞系中的摄取率的顺序为HePG2> HT-29> RAW264.7> A549。孵育8小时后,HePG2细胞吸收复合物1超过60%,而A549仅吸收27.8%。对于复合物8,其吸收趋势类似于复合物1,其被所有四个癌细胞
