Metabolite Identification
Common NamedCTP
DescriptiondCTP, also known as deoxy-CTP, belongs to the class of organic compounds known as pyrimidine 2'-deoxyribonucleoside triphosphates. These are pyrimidine nucleotides with a triphosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. The triphosphate group contains high-energy phosphoanhydride bonds, which liberate energy when hydrolized. dCTP is a drug. dCTP is an extremely weak basic (essentially neutral) compound (based on its pKa). dCTP exists in all living species, ranging from bacteria to humans. Within humans, dCTP participates in a number of enzymatic reactions. In particular, cytidine triphosphate and dCTP can be biosynthesized from uridine triphosphate through its interaction with the enzyme CTP synthase 1. In addition, dCTP can be biosynthesized from dCDP; which is mediated by the enzyme nucleoside diphosphate kinase 6. Like other nucleoside triphosphates, manufacturers recommend that dCTP be stored in aqueous solution at −20 °C. A chemical equation can be written that represents the process:(DNA)n + dCTP ↔ (DNA)n-C + PPiThat is, dCTP has the PPi (pyrophosphate) cleaved off and the dCMP is incorporated into the DNA strand at the 3' end. In humans, dCTP is involved in the metabolic disorder called the beta-ureidopropionase deficiency pathway. Outside of the human body, dCTP has been detected, but not quantified in, several different foods, such as mountain yams, soy beans, wakames, japanese walnuts, and red algaes. This could make dCTP a potential biomarker for the consumption of these foods. DNA polymerase enzymes use this energy to incorporate deoxycytidine into a newly synthesized strand of DNA. Subsequent hydrolysis of the PPi drives the equilibrium of the reaction toward the right side, i.e. incorporation of the nucleotide in the growing DNA chain. Deoxycytidine triphosphate (dCTP) is a nucleoside triphosphate that contains the pyrimidine base cytosine.

Gene Name:
POLB
Uniprot ID:
P06746
Molecular weight:
38177.34
General function:
Involved in nucleotide binding
Specific function:
Plays an essential role in the initiation of DNA replication. During the S phase of the cell cycle, the DNA polymerase alpha complex (composed of a catalytic subunit POLA1/p180, a regulatory subunit POLA2/p70 and two primase subunits PRIM1/p49 and PRIM2/p58) is recruited to DNA at the replicative forks via direct interactions with MCM10 and WDHD1. The primase subunit of the polymerase alpha complex initiates DNA synthesis by oligomerising short RNA primers on both leading and lagging strands. These primers are initially extended by the polymerase alpha catalytic subunit and subsequently transferred to polymerase delta and polymerase epsilon for processive synthesis on the lagging and leading strand, respectively. The reason this transfer occurs is because the polymerase alpha has limited processivity and lacks intrinsic 3' exonuclease activity for proofreading error, and therefore is not well suited for replicating long complexes.
