Rhythmic Nucleotide Synthesis in the Liver: Temporal Segregation of Metabolites
The synthesis of nucleotides in the body is centrally controlled by the liver, via salvage or de novo synthesis. We reveal a pervasive circadian influence on hepatic nucleotide metabolism, from rhythmic gene expression of rate-limiting enzymes to ...

Structural phylogenomics reveals gradual evolutionary replacement of abiotic chemistries by protein enzymes in purine metabolism. [PDF]
The origin of metabolism has been linked to abiotic chemistries that existed in our planet at the beginning of life. While plausible chemical pathways have been proposed, including the synthesis of nucleobases, ribose and ribonucleotides, the cooption of

Nucleobase and nucleoside transport and integration into plant metabolism
Nucleotide metabolism is an essential process in all living organisms. Besides newly synthesized nucleotides, the recycling (salvage) of partially degraded nucleotides i.e.

Cytosolic nucleotidases (cNs) catalyze dephosphorylation of nucleoside 5’-monophosphates and thereby contribute to the regulation of nucleotide levels in cells.

Hydroxycamptothecin (SN38) is a natural plant extract isolated from Camptotheca acuminate. It has a broad spectrum of anticancer activity through inhibition of DNA topoisomerase I, which could affect DNA synthesis and lead to DNA damage. Thus, the action

Importance Of Pyrimidine Nucleotide Salvage Pathways For Dna Synthesis In Skin
Split-thickness rabbit skins were minced and incubated in vitro with radioactive precursors selected to measure do novo and salvage pathways for pyrimidine nucleotide synthesis. In this system, both the salvage precursors [3H]thymidine and [14C]cytidine were incorporated actively into skin DNA and only [14C]cytidine into skin RNA.

Human infections caused by Brucella (called brucellosis) are among the most common zoonoses worldwide with an estimated 500,000 cases each year. Since chronic Brucella infections are extremely difficult to treat, there is an urgent need for more ...
