In the entire metabolic system, there are four reactions that generate high-energy nucleoside triphosphates (ATP or GTP = guanosine triphosphate). The synthesis of CTP occurs through the amination of UTP by the action of CTP synthase. Synthesis, characterization and application of two nucleoside triphosphate analogues, GTPγNH 2 and GTPγF Michael Stumber. This novel strategy without nucleoside protection has been developed to largely simplify synthesis of the nucleoside triphosphates.This demonstrated principle can be applied to the 5′-triphosphate synthesis of both native and modified nucleosides.

The versatility of this process is highlighted in multigram syntheses of d- or l-nucleoside analogs, locked nucleic acids, iminonucleosides, and C2′- and C4′-modified nucleoside analogs. Crystal structures of RNAP reveal two channels: the main channel that contains the downstream DNA and a secondary channel that leads directly to the catalytic site. MeSH terms Adenosine Triphosphate / chemical synthesis* Chemical Phenomena Chemistry Deoxyadenine Nucleotides / chemical synthesis* Methods Phosphorylation Substances Deoxyadenine … The regulation of RNA synthesis by RNA polymerase (RNAP) is essential for proper gene expression. [40], Nucleoside analogues can be used to treat viral infections. Aus Wikipedia, der freien Enzyklopädie Ein Nucleosidtriphosphat ist ein Molekül, das eine stickstoffhaltige Base enthält, die an einen Zucker mit 5 Kohlenstoffatomen (entweder Ribose oder Desoxyribose) gebunden ist , wobei drei Phosphatgruppen an den Zucker gebunden sind.
