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 ...

Disruption of nucleotide biosynthesis reprograms mitochondrial metabolism to inhibit adipogenesis
A key organismal response to overnutrition involves the development of new adipocytes through the process of adipogenesis. Preadipocytes sense changes in the systemic nutrient status and metabolites can directly modulate adipogenesis.

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

Purine Nucleotides in the Regulation of Brown Adipose Tissue Activity
Non-shivering thermogenesis in mammalian brown adipose tissue is a powerful mechanism to defend normothermia in cold climates. To minimize the loss of chemical energy, the central functional component, mitochondrial uncoupling protein 1, UCP1, must be ...
