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. 2013 Oct;33(10):2336-44 Cytidine triphosphate is a pyrimidine nucleoside triphosphate. CPEC is activated by phosphorylation in cells and metabolized to cyclopentenyl cytosine 5′-triphosphate (CPEC-TP). 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 is a pyrimidine ribonucleoside 5'-triphosphate and a cytidine 5'-phosphate.It has a role as an Escherichia coli metabolite and a mouse metabolite.

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 (CTP) synthase 1 is responsible for the catalytic conversion of uridine triphosphate (UTP) to CTP in lymphocytes. Cytidine triphosphate synthase type 2 (CTPS2) had the highest probability to be differentially expressed (p=0.008), and hence was selected for further analysis. When glutamine is the substrate, GTP is required as an allosteric effector to promote catalysis. 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). It is a conjugate acid of a CTP(4-) and a CTP(3-). Journal of Biological Chemistry 2010, 285 (44) , 33727-33736. The presence of CTP synthetase monomer, dimer and tetramer has is synthesized from uridine triphosphate by CTP synthase. CTP synthases also form filamentous structures of different morphologies known as cytoophidia, whose functions in most organisms are unknown. How to abbreviate Cytidine Triphosphate Synthase 1? The activity of this enzyme is elevated in various malignancies including acute lymphocytic leukemia (ALL). Synonyms.

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 … CTPS mediates the conversion of uridine triphosphate into cytidine triphosphate. Cytidine 5'-triphosphate synthase catalyses the ATP-dependent formation of CTP from UTP with tither ammonia or glutamine as the source of nitrogen. 3, pp. The isolates were chosen as representatives of three demes as determined by several criteria including divergence in the rDNA repeat unit. 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. Cytidine triphosphate (CTP) synthase 1 is responsible for the catalytic conversion of uridine triphosphate to CTP in lymphocytes [ 1 ]. Regulation of Human Cytidine Triphosphate Synthetase 2 by Phosphorylation. 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). Ubiquitination and filamentous structure of cytidine triphosphate synthase. multidrug resistance Recently, cytidine-5'-triphosphate (CTP) synthase was discovered to form a filamentous structure that is evolutionarily conserved from flies to humans.
