  荧光标记核苷酸在DNA合成测序以及单分子测序中的应用

  摘要：

  本发明公开了一种荧光标记核苷酸在DNA合成测序及单分子测序中的应用，所述荧光标记核苷酸典型结构#imgabs0#其中Base为U,C,A,G四个不同的碱基；R为苯环、炔基或乙烯基；Cleavable Linker为三氮烯连接单元；R1是将三氮烯连接单元与荧光素连接在一起的化学分子基团，Dye是荧光染料。该类荧光标记核苷酸参与DNA延伸、断裂后，残留在碱基上的基团只有苯(胺)基、炔基、乙烯基等含π‑电子基团。本发明在DNA合成测序及单分子测序中，荧光标记核苷酸在参与延伸并断裂反应后，在DNA链上的残基只有苯(胺)基、炔基、乙烯基，有助于DNA测序读长更长且错误率更低。

  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.
