Journal of Biological Chemistry 2010, 285 (44) , 33727-33736. CTPS1, one of two mammalian CTP synthases (the other being CTPS2), catalyzes the formation of CTP, an essential nucleotide for DNA and RNA synthesis (Veillette and Davidson 2014). N2 - Cytidine triphosphate (CTP) synthase is one of the key enzymes in pyrimidine nucleotide anabolic pathways. Cytidine triphosphate synthetase UniRule annotation. CTP synthetase is the rate-limiting enzyme in the synthesis of cytosine nucleotides, which play an important role in various metabolic processes and provide the precursors necessary for the synthesis … 6 Cyclopentenyl cytosine (CPEC) is an analog of cytidine. CTP is a pyrimidine ribonucleoside 5'-triphosphate and a cytidine 5'-phosphate.It has a role as an Escherichia coli metabolite and a mouse metabolite. Recently, cytidine-5'-triphosphate (CTP) synthase was discovered to form a filamentous structure that is evolutionarily conserved from flies to humans. 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. CTPS mediates the conversion of uridine triphosphate into cytidine triphosphate. Cytidine triphosphate (CTP) synthase 1 is responsible for the catalytic conversion of uridine triphosphate (UTP) to CTP in lymphocytes. CTP synthases also form filamentous structures of different morphologies known as cytoophidia, whose functions in most organisms are unknown. Regulation of Human Cytidine Triphosphate Synthetase 2 by Phosphorylation. has been purified over 31000-fold to homogeneity with 17% recovery from rat liver cytosol, using high-performance liquid chromatography (HPLC) techniques. ABSTRACT.

Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. CTP synthetase catalyses the conversion of uridine triphosphate (UTP) into cytidine triphosphate (CTP), which is one of the only two pathways for synthesizing CTP. Cytidine triphosphate is a pyrimidine nucleoside triphosphate. Cytidine diphosphate diacylglycerol (CDP-DAG) is a central lipid intermedi-ate for several pathways in both prokaryotes and eukaryotes, being produced by CDP-DAG synthase (CDS). 2 ways to abbreviate Cytidine Triphosphate Synthase 1 updated 2020. CTP synthetase is a key enzyme in the metabolism of cytosine (deoxy)ribonucleotides. When glutamine is the substrate, GTP is required as an allosteric effector to promote catalysis. The activity of this enzyme is elevated in various malignancies including acute lymphocytic leukemia (ALL). 10, No. Microarray probesets 8.

Here, we provide evidence that stimulation or inhibition of protein kinase A and protein kinase C does not alter the phosphorylation of endogenous human CTPS1 in … CPEC-TP is a noncompetitive inhibitor of CTP synthase and blocks CTP synthesis. CTPS is an important modulator of lymphocyte proliferation and has been identified as a potential therapeutic target for the treatment of acute lymphoblastic leukemia. Ubiquitination and filamentous structure of cytidine triphosphate synthase. Cytidine triphosphate synthase type 2 (CTPS2) had the highest probability to be differentially expressed (p=0.008), and hence was selected for further analysis. against this neglected disease. Cytidine is a pyrimidine nucleoside in which cytosine is attached to ribofuranose via a beta-N(1)-glycosidic bond. How to abbreviate Cytidine Triphosphate Synthase 1? 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. J:222216 Tang R, et al., CTP synthase 1, a smooth muscle-sensitive therapeutic target for effective vascular repair. CPEC is activated by phosphorylation in cells and metabolized to cyclopentenyl cytosine 5′-triphosphate (CPEC-TP). The metabolic enzyme CTP synthase forms cytoskeletal filaments. The enzyme, encoded by the CTPS1 gene, is important in the biosynthesis of phospholipids and nucleic acids, and plays a key role in cell growth, development, and tumorigenesis (summary by Thomas et al., 1989). In mammalian cells, there are 2 isozymes of CTP synthase, that is, CTPS1 and CTPS2.6 Cyclopentenyl cytosine (CPEC) is an analog of cytidine. Regulates intracellular CTP levels through interactions with … Cytidine 5′-triphosphate synthase catalyses the ATP-dependent formation of CTP from UTP using either ammonia or l-glutamine as the source of nitrogen. The activity of this enzyme is elevated in various malignancies including acute lymphocytic leukemia (ALL). It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. A830031M15Rik, CTPsH ...

IPR027417 P-loop containing nucleoside triphosphate hydrolase. 3, pp. 2013 Oct;33(10):2336-44 Synonyms. is synthesized from uridine triphosphate by CTP synthase. 108-114. CPEC is activated by phosphorylation in cells and metabolized to cyclopentenyl cytosine 5′-triphos-phate (CPEC-TP). Arterioscler Thromb Vasc Biol. CTP plays a central role in nucleotide and lipid biosynthesis and is synthesized de novo by the catalytic action of CTP synthase (CTPS). Cytidine triphosphate synthetase (CTPS) catalyzes the rate-limiting step in the de novo synthesis of CTP, and both the yeast and human enzymes have been reported to be regulated by protein kinase A or protein kinase C phosphorylation. The enzyme plays a major role in the pyrimidine ribonucleotide de novo pathway and the salvage pathway of the nucleoside uridine. In a cytidine deaminase-deficient mutant, which cannot convert cytidine to uridine, cytidine was able to repress CTP synthetase but was no longer able to repress genes of thepyr operon. Other names CTP; Cytidine-5'-triphosphate; Cytidine 5'-(tetrahydrogen triphosphate) 7 CTPS2 suppression increases resistance to 5FU and FUDR Thirteen colorectal cancer cell lines (listed in … In mammalian cells, there are 2 isozymes of CTP synthase, that is, CTPS1 and CTPS2. cytidine triphosphate synthetase: Abbreviation Variation Long Form Variation ...

Fly: Vol. When glutamine is the substrate, GTP is required as an allosteric effector to promote catalysis. Abstract Cytidine triphosphate (CTP) synthase is one of the key enzymes in pyrimidine nucleotide anabolic pathways. Cytidine triphosphate (CTP) synthase 1 is responsible for the catalytic conversion of uridine triphosphate to CTP in lymphocytes [ 1 ]. The isolates were chosen as representatives of three demes as determined by several criteria including divergence in the rDNA repeat unit. The cytidine triphosphate synthetase genes from three diverse strains of Giardia duodenalis have been sequenced and found to vary significantly from one another. Cytidine 5'-triphosphate synthase catalyses the ATP-dependent formation of CTP from UTP with tither ammonia or glutamine as the source of nitrogen. All nucleic 99. cDNA 99. Deficiency in cytidine 5-prime triphosphate synthase 1 (CTPS1) causes a combined immunodeficiency affecting both cellular and humoral immunity. Its deficiency may result in mutator effects and multidrug resistance. This reaction is important for the biosynthesis of nucleic acids, playing a key role in lymphocyte function and turnover. Cytidine 5′‐triphosphate synthase catalyses the ATP‐dependent formation of CTP from UTP using either ammonia or l ‐glutamine as the source of nitrogen. (2016). multidrug resistance 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). However, nothing is known about the single T. brucei CDS gene (Tb927.7.220/EC 2.7.7.41) or its activity. Recently, cytidine-5'-triphosphate (CTP) synthase was discovered to form a filamentous structure that is evolutionarily conserved from flies to humans. It is a conjugate acid of a CTP(4-) and a CTP(3-). Interestingly, induction of the formation of CTP synthase filament is responsive to starvation or glutamine depletion.
