CTPS mediates the conversion of uridine triphosphate into cytidine triphosphate. Cytidine 5′‐triphosphate synthase catalyses the ATP‐dependent formation of CTP from UTP using either ammonia or l ‐glutamine as the source of nitrogen. N2 - Cytidine triphosphate (CTP) synthase is one of the key enzymes in pyrimidine nucleotide anabolic pathways. Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Cytidine triphosphate Names IUPAC name [(2R,3S,4R,5R)-5-(4-amino-2-oxopyrimidin-1-yl)-3,4-dihydroxyoxolan-2-yl]methyl(hydroxy-phosphonooxyphosphoryl)hydrogen phosphate. ABSTRACT. All nucleic 99. cDNA 99. 2013 Oct;33(10):2336-44 Deficiency in cytidine 5-prime triphosphate synthase 1 (CTPS1) causes a combined immunodeficiency affecting both cellular and humoral immunity. 3, pp. Recently, cytidine-5'-triphosphate (CTP) synthase was discovered to form a filamentous structure that is evolutionarily conserved from flies to humans. CTP plays a central role in nucleotide and lipid biosynthesis and is synthesized de novo by the catalytic action of CTP synthase (CTPS). The presence of CTP synthetase monomer, dimer and tetramer has 6 Cyclopentenyl cytosine (CPEC) is an analog of cytidine. The activity of this enzyme is elevated in various malignancies including acute lymphocytic leukemia (ALL). Regulates intracellular CTP levels through interactions with … CPEC-TP is a noncompetitive inhibitor of CTP synthase and blocks CTP synthesis. Cytidine triphosphate synthase type 2 (CTPS2) had the highest probability to be differentially expressed (p=0.008), and hence was selected for further analysis. Cytidine triphosphate synthase catalyzes the synthesis of cytidine 5'-triphosphate (CTP) from uridine 5'-triphosphate (UTP), the final step in the production of cytidine nucleotides. When glutamine is the substrate, GTP is required as an allosteric effector to promote catalysis. The catalytic conversion of UTP to CTP is accomplished by the enzyme cytidine-5-prime-triphosphate synthetase (UTP:L-glutamine amido ligase; EC 6.3.4.2). The enzyme plays a major role in the pyrimidine ribonucleotide de novo pathway and the salvage pathway of the nucleoside uridine. CPEC is activated by phosphorylation in cells and metabolized to cyclopentenyl cytosine 5′-triphos-phate (CPEC-TP). The cytidine triphosphate synthetase genes from three diverse strains of Giardia duodenalis have been sequenced and found to vary significantly from one another. Synonyms. cytidine 5'-triphosphate synthase 2. CTP synthases also form filamentous structures of different morphologies known as cytoophidia, whose functions in most organisms are unknown. multidrug resistance has been purified over 31000-fold to homogeneity with 17% recovery from rat liver cytosol, using high-performance liquid chromatography (HPLC) techniques. CPEC is activated by phosphorylation in cells and metabolized to cyclopentenyl cytosine 5′-triphosphate (CPEC-TP). 2 ways to abbreviate Cytidine Triphosphate Synthase 1 updated 2020.

The most popular abbreviation for Cytidine Triphosphate Synthase 1 … The metabolic enzyme CTP synthase forms cytoskeletal filaments. Cytidine triphosphate (CTP) synthase 1 is responsible for the catalytic conversion of uridine triphosphate to CTP in lymphocytes [ 1 ]. The activity of this enzyme is elevated in various malignancies including acute lymphocytic leukemia (ALL). CTP synthetase catalyses the conversion of uridine triphosphate (UTP) into cytidine triphosphate (CTP), which is one of the only two pathways for synthesizing CTP. 108-114.
