📜对氟苯甲醇置于recombinant Giardia Lamblia Phosphoglucomutase 1,烟酰胺腺嘌呤双核苷酸磷酸盐,Magnesium Chloride体系中,化学反应生成 α-D-吡喃葡萄糖6-磷酸 参考文献:A Deeply Divergent Phosphoglucomutase (Pgm) Of Giardia Lamblia Has Both Pgm And Phosphomannomutase Activities 标题:A Deeply Divergent Phosphoglucomutase (Pgm) Of Giardia Lamblia Has Both Pgm And Phosphomannomutase Activities 摘要:贾第虫(giardia Lamblia)是引起腹泻的重要寄生虫,其利用葡萄糖的活化形式合成糖原,以及利用甘露糖的活化形式合成甘油磷酸肌醇锚.葡萄糖活化的一个必要步骤是通过磷酸葡萄糖变位酶(pgm)将葡萄糖-6-磷酸异构化为葡萄糖-1-磷酸.同样,磷酸甘露糖变位酶(pmm)则将甘露糖-6-磷酸转化为甘露糖-1-磷酸.虽然贾第虫的全基因组序列预测出了两个pgm候选基因,但并没有发现pmm候选基因.本研究测试的假设是,这两个贾第虫pgm候选基因中至少有一个同时具有pgm和pmm活性,正如细菌pgm同源物所描述的那样.非变性凝胶显示贾第虫有两种具有pgm活性的蛋白,其中一种也具有pmm活性.系统发育分析表明,这两种贾第虫pgm候选基因中的一种(gl-Pgm1)与其他真核生物的pgm共享近期共同祖先,而另一种贾第虫pgm候选基因(gl-Pgm2)则与之有很大差异.gl-Pgm1和gl-Pgm2均能拯救酿酒酵母(saccharomyces Cerevisiae)中的pgm1δ/pgm2δ双缺失株,而只有gl-Pgm2能拯救酿酒酵母的温敏pmm突变株(sec53-Ts).重组gl-Pgm1仅具有pgm活性,而gl-Pgm2则同时具有pgm和pmm活性.我们得出结论,Gl-Pgm1表现为一种传统的真核生物pgm,而gl-Pgm2是一种具有pmm活性的新的真核生物pgm.

专利号:US-5824472-A 优先权日:1986-03-24 标 题 :Process for the synthesis of sugar nucleotides using recombinant-DNA methods 发明人:BETLACH MICHAEL R; DOHERTY DANIEL H; VANDERSLICE REBECCA W 权利人:MONSANTO CO 摘要:A recombinant-DNA mediated method for the synthesis of sugar nucleotides is disclosed. This method utilizes portable DNA sequences capable of directing the microbial synthesis of various enzymes that catalyze the synthesis of sugar nucleotides, including UDP-glucose, UDP-glucuronic acid and GDP-mannose. The sugar moieties of these sugar nucleotides may subsequently be incorporated into industrially-useful polysaccharides such as xanthan gum. It has been found that vectors containing the portable DNA sequences described herein are capable both of causing sugar nucleotide production in microorganisms previously incapable of such synthesis and of causing increased sugar nucleotide production in organisms capable of synthesizing small quantities of these compounds. In particular, plasmids pAS7, pAS9 and pTS13 are disclosed. These plasmids are capable of directing sugar nucleotide synthesis in various hosts, including Xanthomonas sp. such as X. campestris and other organisms such as E. coli and various Pseudomonas sp.
