  溶液中具有生理活性的二核苷多磷酸盐的构象是什么？NMR和分子动力学模拟对游离二核苷多磷酸的构象分析†

  摘要：

  二核苷多磷酸盐或二核苷酸（Np n N'； N，N'= A，U，G，C；n = 2-7）是天然存在的生理活性化合物。尽管对二核苷酸的兴趣以及它们的构象与其生物学功能的相关性，但是对二核苷酸的构象的研究还不够充分。因此，在这里，我们通过各种NMR技术对一系列Np n N'Na +盐（N = A，G，U，C； N'= A，G，U，C；n = 2–5）进行了构象分析。。如NMR所示，除Up 4/5 U外，所有研究的二核苷酸均在水溶液中形成分子内碱基堆积相互作用。Np n中糖苷角周围的构象发现N's是抗/高抗性，并且发现C4'-C5'，C5'-O5'键周围的优选构象是gauche – gauche（gg）。Np n N's中的核糖部分显示出对S构象的偏爱，但是当连接到胞嘧啶时，核糖环则优先选择N构象。然而，在任何二核苷酸中均未观察到核糖部分的主要构象。Ap 2 A和Ap 4 A Na +盐的分子动力学模拟支持了实验结果。此外，针对Ap

  The present invention relates to a probe compound that can comprise any substrate or metabolite of an enzymatic reaction in addition to an indicator component, such as, for example, a fluorescence dye, or the like. Moreover, the present invention relates to means for detecting enzymes in form of an array, which comprises any number of probe compounds of the invention which each comprise a different metabolite of interconnected metabolites representing the central pathways in all forms of life. Moreover, the present invention relates to a method for detecting enzymes involving the application of cell extracts or the like to the array of the invention which leads to reproducible enzymatic reactions with the substrates. These specific enzymatic reactions trigger the indicator (e.g. a fluorescence signal) and bind the enzymes to the respective cognate substrates. Moreover, the invention relates to means for isolating enzymes in form of nanoparticles coated with the probe compound of the invention. The immobilisation of the cognate substrates or metabolites on the surface of nanoparticles by means of the probe compounds allows capturing and isolating the respective enzyme, e.g. for subsequent sequencing.

  A method, computer-readable medium, and system for identifying one or more metabolites associated with a disease, comprising: comparing gene expression data from diseased cells to gene expression data from control cells in order to deduce genes that are differentially-regulated in the diseased cells relative to the control cells; based on enzyme function and pathway data for all human metabolites that utilize the genes that are differentially-regulated in the disease cells, identifying one or more metabolites whose intracellular levels are higher or lower in diseased cells than in control cells, and thereby associating the one or more metabolites with the disease.
