DNA as an information storage system is simple and at the same time complex owing to the various different arrangements of the four natural nucleotides.[1] The DNA synthesis by DNA polymerases is intriguing, since these enzymes are able to catalyze the elongation of the primer strand by recognizing the DNA template and selecting the corresponding ...

Nucleotide-decorated AuNPs as probes for nucleotide-binding proteins [PDF]
AbstractGold nanoparticles (AuNPs) decorated with biologically relevant molecules have variety of applications in optical sensing of bioanalytes. Coating AuNPs with small nucleotides produces particles with high stability in water, but functionality-compatible strategies are needed to uncover the full potential of this type of conjugates.

Synthesis and Antiviral Activity of a Series of 2′-C-Methyl-4′-thionucleoside Monophosphate Prodrugs
The NS5B RNA-dependent RNA polymerase of the hepatitis C virus (HCV) is a validated target for nucleoside antiviral drug therapy. We endeavored to synthesize and test a series of 4′-thionucleosides with a monophosphate prodrug moiety for their antiviral ...

Thermophilic phosphoribosyltransferases Thermus thermophilus HB27 in nucleotide synthesis
Phosphoribosyltransferases are the tools that allow the synthesis of nucleotide analogues using multi-enzymatic cascades. The recombinant adenine phosphoribosyltransferase (TthAPRT) and hypoxanthine phosphoribosyltransferase (TthHPRT) from Thermus ...

Effect of nucleotides on broiler performance and carcass yield
This study aimed at evaluating the effect of nucleotides on the performance and carcass yield of broilers fed diets with no antibiotic growth promoters (AGP), anticoccidials, or animal feedstuffs. In the trial, 600 Ross 308 male broilers were distributed

CTP Synthase 2 From Arabidopsis thaliana Is Required for Complete Embryo Development
Pyrimidine de novo synthesis is an essential pathway in all organisms. The final and rate-limiting step in the synthesis of the nucleotide cytidine triphosphate (CTP) is catalyzed by CTP synthase (CTPS), and Arabidopsis harbors five isoforms.

An Allosteric Inhibitory Site Conserved in the Ectodomain of P2X Receptor Channels
P2X receptors constitute a gene family of cation channels gated by extracellular ATP. They mediate fast ionotropic purinergic signaling in neurons and non-excitable cell types in vertebrates.
