WebMay 15, 2024 · The CTP-generating enzyme CTP synthase forms long filamentous structures termed cytoophidia in bacteria, yeast, fruit flies and human cells independent of its catalytic activity. However, the amino acid determinants for protein-protein interaction necessary for polymerisation remained unknown. WebMar 3, 2024 · Cancer cell proliferation is supported by high metabolic activity. Targeting metabolic pathways is therefore a strategy to suppress cancer cell growth and survival. Glutamine is a key metabolite that supports a plethora of anabolic, growth-promoting reactions in the cell.

WebCTP is formed by CTP synthetase by transferring an amino group from glutamine to UTP (Figure 3). Pyrimidine biosynthesis is regulated by feedback inhibition of the first enzyme carbamoyl phosphate synthetase by the end products UMP, UDP, and UTP of the pathway. Given their importance in the cell, the synthesis and degradation of nucleoside triphosphates is under tight control. This section focuses on nucleoside triphosphate metabolism in humans, but the process is fairly conserved among species. Nucleoside triphosphates cannot be absorbed well, so … See more A nucleoside triphosphate is a nucleoside containing a nitrogenous base bound to a 5-carbon sugar (either ribose or deoxyribose), with three phosphate groups bound to the sugar. They are the molecular precursors of both See more ATP as a source of cellular energy ATP is the primary energy currency of the cell. Despite being synthesized through the metabolic … See more • Biology • Chromosome • Gene • Genetics See more The term nucleoside refers to a nitrogenous base linked to a 5-carbon sugar (either ribose or deoxyribose). Nucleotides are nucleosides covalently linked to one or more phosphate groups. To provide information about the number of phosphates, … See more The cellular processes of DNA replication and transcription involve DNA and RNA synthesis, respectively. DNA synthesis uses dNTPs as … See more Nucleoside analogues can be used to treat viral infections.
