Abstract Cytidine triphosphate (CTP) synthase is one of the key enzymes in pyrimidine nucleotide anabolic pathways. Its deficiency may result in mutator effects and multidrug resistance. Cytidine 5′-triphosphate synthase catalyses the ATP-dependent formation of CTP from UTP using either ammonia or l-glutamine as the source of nitrogen. How to abbreviate Cytidine Triphosphate Synthase 1? The activity of this enzyme is elevated in various malignancies including acute lymphocytic leukemia (ALL). Cytidine 5'-triphosphate synthase catalyses the ATP-dependent formation of CTP from UTP with tither ammonia or glutamine as the source of nitrogen. 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. 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). A830031M15Rik, CTPsH ... CTPS2, CTP synthase 2 Orthology source: HomoloGene, HGNC Links ... IPR027417 P-loop containing nucleoside triphosphate hydrolase. Interestingly, induction of the formation of CTP synthase filament is responsive to starvation or glutamine depletion. Target-specific ELISA kits are available from a variety of manufacturers and can help streamline your immunodetection experiments. 2013 Oct;33(10):2336-44 Short name: CTPS UniRule annotation. 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. Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. CTP synthetase is a key enzyme in the metabolism of cytosine (deoxy)ribonucleotides. CPEC is activated by phosphorylation in cells and metabolized to cyclopentenyl cytosine 5′-triphosphate (CPEC-TP). is synthesized from uridine triphosphate by CTP synthase. Cytidine is a pyrimidine nucleoside in which cytosine is attached to ribofuranose via a beta-N(1)-glycosidic bond. Recently, cytidine-5'-triphosphate (CTP) synthase was discovered to form a filamentous structure that is evolutionarily conserved from flies to humans. 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. Cytidine triphosphate synthase type 2 (CTPS2) had the highest probability to be differentially expressed (p=0.008), and hence was selected for further analysis. 7 CTPS2 suppression increases resistance to 5FU and FUDR Thirteen colorectal cancer cell lines (listed in … CTPS mediates the conversion of uridine triphosphate into cytidine triphosphate. Here, we provide evidence that stimulation or inhibition of prote ….

Cytidine triphosphate synthetase UniRule annotation. When glutamine is the substrate, GTP is required as an allosteric effector to promote catalysis. The cytidine triphosphate synthetase genes from three diverse strains of Giardia duodenalis have been sequenced and found to vary significantly from one another. 2013 Oct;33(10):2336-44 Arterioscler Thromb Vasc Biol. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. 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). 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. However, nothing is known about the single T. brucei CDS gene (Tb927.7.220/EC 2.7.7.41) or its activity. ABSTRACT. has been purified over 31000-fold to homogeneity with 17% recovery from rat liver cytosol, using high-performance liquid chromatography (HPLC) techniques. In this study we show TbCDS is functional by The activity of this enzyme is elevated in various malignancies including acute lymphocytic leukemia (ALL).

Ubiquitination and filamentous structure of cytidine triphosphate synthase. Cytidine triphosphate (CTP) synthase 1 is responsible for the catalytic conversion of uridine triphosphate (UTP) to CTP in lymphocytes. In mammalian cells, there are 2 isozymes of CTP synthase, that is, CTPS1 and CTPS2.6 Cyclopentenyl cytosine (CPEC) is an analog of cytidine. Deficiency in cytidine 5-prime triphosphate synthase 1 (CTPS1) causes a combined immunodeficiency affecting both cellular and humoral immunity. against this neglected disease.

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). 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 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. 6 Cyclopentenyl cytosine (CPEC) is an analog of cytidine. In mammalian cells, there are 2 isozymes of CTP synthase, that is, CTPS1 and CTPS2.
