Cytidine triphosphate
Cytidine triphosphate (CTP), also known as 5-CTP, is pyrimidine nucleoside triphosphate. Formally, CTP is an ester of cytidine and triphosphoric acid. It belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. CTP, much like ATP, consists of a base (cytosine), a ribose sugar, and three phosphate groups. CTP is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions. CTP exists in all living species, ranging from bacteria to plants to humans and is used in the synthesis of RNA via RNA polymerase. Another enzyme known as cytidine triphosphate synthetase (CTPS) mediates the conversion of uridine triphosphate (UTP) into cytidine triphosphate (CTP) which is the rate-limiting step of de novo CTP biosynthesis. CTPS catalyzes a complex set of reactions that include the ATP-dependent transfer of the amide nitrogen from glutamine (i.e., glutaminase reaction) to the C-4 position of UTP to generate CTP. GTP stimulates the glutaminase reaction by accelerating the formation of a covalent glutaminyl enzyme intermediate. CTPS activity regulates the intracellular rates of RNA synthesis, DNA synthesis, and phospholipid synthesis. CTPS is an established target for a number of antiviral, antineoplastic, and antiparasitic drugs. CTP also acts as an inhibitor of the enzyme known as aspartate carbamoyltransferase, which is used in pyrimidine biosynthesis. CTP also reacts with nitrogen-containing alcohols to form coenzymes that participate in the formation of phospholipids. In particular, CTP is the direct precursor of the activated, phospholipid pathway intermediates CDP-diacylglycerol, CDP-choline, and CDP-ethanolamine ((PMID: 18439916). CDP-diacylglycerol is the source of the phosphatidyl moiety for phosphatidylserine, phosphatidylethanolamine, and phosphatidylcholine (synthesized by way of the CDP-diacylglycerol pathway) as well as phosphatidylglycerol, cardiolipin, and phosphatidylinositol (PMID: 18439916). Cytidine triphosphate, also known as 5-ctp or cytidine 5-triphosphoric acid, is a member of the class of compounds known as pentose phosphates. Pentose phosphates are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. Cytidine triphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa). Cytidine triphosphate can be found in a number of food items such as lowbush blueberry, black radish, american pokeweed, and cherry tomato, which makes cytidine triphosphate a potential biomarker for the consumption of these food products. Cytidine triphosphate can be found primarily in cellular cytoplasm, as well as throughout all human tissues. Cytidine triphosphate exists in all living species, ranging from bacteria to humans. In humans, cytidine triphosphate is involved in several metabolic pathways, some of which include cardiolipin biosynthesis cl(i-14:0/i-17:0/i-16:0/i-21:0), cardiolipin biosynthesis cl(a-13:0/a-21:0/i-22:0/i-17:0), phosphatidylethanolamine biosynthesis PE(18:2(9Z,12Z)/24:0), and cardiolipin biosynthesis cl(i-13:0/a-21:0/a-15:0/i-16:0). Cytidine triphosphate is also involved in several metabolic disorders, some of which include sialuria or french type sialuria, tay-sachs disease, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and g(m2)-gangliosidosis: variant B, tay-sachs disease. Cytidine triphosphate is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions. Cytidine triphosphate is a coenzyme in metabolic reactions like the synthesis of glycerophospholipids and glycosylation of proteins . Cytidine 5′-triphosphate (Cytidine triphosphate; 5'-CTP) is a nucleoside triphosphate and serves as a building block for nucleotides and nucleic acids, lipid biosynthesis. Cytidine triphosphate synthase can catalyze the formation of cytidine 5′-triphosphate from uridine 5′-triphosphate (UTP). Cytidine 5′-triphosphate is an essential biomolecule?in the de novo?pyrimidine biosynthetic pathway in?T. gondii[1].

Pseudouridine 5'-phosphate
Pseudouridine (5-ribosyluracil) is a ubiquitous yet enigmatic constituent of structural RNAs (transfer, ribosomal, small nuclear, and small nucleolar). Although pseudouridine (psi) was the first modified nucleoside to be discovered in RNA, and is the most abundant, its biosynthesis and biological roles have remained poorly understood since its identification as a "fifth nucleoside" in RNA. Recently, a combination of biochemical, biophysical, and genetic approaches has helped to illuminate the structural consequences of psi in polyribonucleotides, the biochemical mechanism of U-->psi isomerization in RNA, and the role of modification enzymes (psi synthases) and box H/ACA snoRNAs, a class of eukaryotic small nucleolar RNAs, in the site-specific biosynthesis of psi. Through its unique ability to coordinate a structural water molecule via its free N1-H, psi exerts a subtle but significant "rigidifying" influence on the nearby sugar-phosphate backbone and also enhances base stacking. These effects may underlie the biological role of most (but perhaps not all) of the psi residues in RNA. Certain genetic mutants lacking specific psi residues in tRNA or rRNA exhibit difficulties in translation, display slow growth rates, and fail to compete effectively with wild-type strains in mixed culture. In particular, normal growth is severely compromised in an Escherichia coli mutant deficient in a pseudouridine synthase responsible for the formation of three closely spaced psi residues in the mRNA decoding region of the 23S rRNA. Such studies demonstrate that pseudouridylation of RNA confers an important selective advantage in a natural biological context. PMID: 10902565 [HMDB].

N5-Carboxyaminoimidazole ribonucleotide
N5-Carboxyaminoimidazole ribonucleotide is an intermediate in purine nucleotides de novo biosynthesis. Purine nucleotides participate in many aspects of cellular metabolism including the structure of DNA and RNA, serving as enzyme cofactors, functioning in cellular signaling, acting as phosphate group donors, and generating cellular energy. Maintenance of the proper balance of intracellular pools of these nucleotides is critical to normal function. This occurs through a combination of de novo biosynthesis and salvage pathways for pre-existing purine bases, nucleosides and nucleotides. The de novo biosynthetic pathway for purine nucleotides is highly conserved among organisms, but its regulation and the organization of the genes encoding the enzymes vary. The fourteen step pathway contains ten steps that branch at inosine-5-phosphate to form adenosine-5-phosphate and guanosine-5-phosphate, each in two steps.

D-Xylulose-5-phosphate
Xylulose 5-phosphate (Xu-5-P) is a metabolite of the hexose monophosphate pathway that activates protein phosphatase 2A to mediate the acute effects of carbohydrate feeding on the glycolytic pathway, as well as the coordinate long-term control of the enzymes required for fatty acid and triglyceride synthesis. Xu-5-P is the signal for the coordinated control of lipogenesis. Feeding carbohydrate causes levels of liver glucose, Glucose-6-phosphate (Glc-6-P), and Fructose-6-phosphate (Fru-6-P) to rise. Elevation of Fru-6-P leads to elevation of Xu-5-P in reactions catalyzed by the near-equilibrium isomerases of the nonoxidative portion of the hexose monophosphate pathway (ribulose 5-phosphate (Ru5P) epimerase [EC 5.1.3.1], ribose 5-phosphate (Rib5P) isomerase [EC 5.3.1.6], transaldolase [EC 2.2.1.2], and transketolase [EC 2.2.1.1]). The elevation of Xu-5-P is the coordinating signal that both acutely activates phosphofructokinase [PFK; EC 2.7.1.11] in glycolysis and promotes the action of the transcription factor carbohydrate responsive element binding protein (ChREBP) to increase transcription of the genes for the enzymes of lipogenesis, the hexose monophosphate shunt, and glycolysis, all of which are required for the de novo synthesis of fat.
