malfunction
-
cytosolic 5'-nucleotidase cN-II is implicated in drug resistance in patients and dephosphorylates 5-fluoro-dUMP, 3'-azido-3-dTMP, 2'-chloro-2'-deoxyAMP, and related compounds, which represent the monophosphorylated forms of nucleoside prodrugs
metabolism
physiological function
additional information
metabolism
-
the key and rate-limiting enzyme in the ectonucleotidase pathway is ecto-5'-nucleotidase, which catalyzes the final step of dephosphorylation of AMP to adenosine
metabolism
-
5'-nucleotidases are involved in the purine and pyrimidine nucleotide metabolic pathways, overview. CD73 enzymatic activity is implicated in two major extracellular metabolic pathways with distinct physiological roles, extracellular adenosine nucleotide and NAD+ metabolism
metabolism
-
Trichomonas foetus is devoid of the ability to synthesize purine nucleotides de novo, depending instead on salvaging purines from the host environment. Ecto-5'-nucleotidase catalyzes the final step of extracellular nucleotide degradation, the hydrolysis of nucleoside 5'-monophosphates to the corresponding nucleosides and phosphate

-

-
physiological function
-
the ecto-5'-nucleotidase plays a role in the control of extracellular nucleotide concentrations in the cell and is involved in the release of free adenosine into extracellular medium
physiological function
-
the enzyme plays a role in the generation of extracellular adenosine, a key modulator of male fertility
physiological function
-
the enzyme plays a role in the generation of extracellular adenosine, a key modulator of male fertility
physiological function
-
cytosolic 5'-nucleotidase II catalyzes the dephosphorylation of 6-hydroxypurine nucleoside 5'-monophosphates and participates in the regulation of purine nucleotide pools within the cell
physiological function
-
5'-nucleotidase UshA is required for growth when nucleotides are provided as the sole source of phosphate, a condition that is likely relevant to bacterial growth in the wild
physiological function
-
5'-nucleotidase activities regulate the quantity of nucleotides generated from both de novo and salvage pathways, overview. 5'-Nucleotidase designates a set of enzymes, which catalyze the hydrolysis of ribonucleoside and deoxyribonucleoside monophosphates into the corresponding nucleosides plus phosphate. 5'-Nucleotidases are classified according to subcellular localization, nucleobase specificity and their ability to hydrolyze deoxynucleoside monophosphate substrates. Membrane-bound 5'-nucleotidases are ectoenzymes principally involved in salvage of extracellular nucleosides, and often display a preference toward adenosine monophosphate, thereby modulating signal transduction cascades involving purinergic receptors. Cytosolic 5'-nucleotidases are members of the haloacid dehalogenase superfamily of enzymes, which are two-domain proteins containing a modified Rossman fold as the core and a variable cap structure. Extracellular and intracellular 5'-nucleotidase activities participate in purine and pyrimidine salvage to support balanced synthesis of nucleotides, which is critical for maintaining high fidelity DNA replication. The major physiological roles for CD73 in extracellular adenosine metabolism are severalfold, overview. cNII is subject to complex allosteric regulation
physiological function
-
ISN1 is responsible for virtually all IMP 5'-nucleotidase activity in budding yeast cells and is required for cells to release inosine into the culture medium
physiological function
-
upon blockade of enzyme by concanavalin A, the strength of adhesion to different extracellular matrix proteins is not altered, but at the same time the invasion ability of the cells is decreased. Knocking down the enzyme in melanoma cells does not influence cell invasion but abolishes their migration on tenascin C, indicating that an enzyme-tenascin C complex is involved in cell migration and invasion and thus in the regulation of melanoma progression
physiological function
-
the two domains can be expressed individually in Escherichia coli and fold independently. The C-terminal domain, which contains the substrate-binding pocket, is completely inactive while the N-terminal domain with the two-metal-ion-centers and the core catalytic residues exhibits significant activity, especially towards substrates with activated phosphate bonds such as ATP, ADP, 4-nitrophenyl phosphate. The two domains do not reconstitute the full-length protein from the two folded individual domains
physiological function
transgenic mice expressing a dominant active mutant of downstream regulatory element antagonist modulator, daDREAM, show a drastic reduction of the amount of transcript of Ca2+-activated nucleotidase. Ca2+-activated nucleotidase down-regulation is also found in neuroblastoma SH-SY5Y cells stably overexpressing wild type DREAM or daDREAM, thus providing a simple cell model to investigate the protein maturation pathway. The down-regulation of CANT1 is associated with reduced protein secretion and increased degradation rates
physiological function
-
in neonatal blood plasma, soluble 5'-nucleotidase and alkaline phosphatase mediate conversion of AMP to adenosine, whereas soluble adenosine deaminase catabolizes adenosine to inosine. Newborn blood plasma demonstrates substantially higher adenosine-generating 5'-nucleotidase and alkaline phosphatase activity and lower metabolizing adenosine deaminase activity than adult plasma. Supplementation with AMP inhibits whereas selective pharmacologic inhibition of 5'-nucleotidase enhances Toll-like receptor-mediated tumor necrosis factor TNF-alpha production in neonatal whole blood
physiological function
-
the ecto-5'-nucleotidase plays a role in the control of extracellular nucleotide concentrations in the cell and is involved in the release of free adenosine into extracellular medium
-
physiological function
-

-
additional information
-
the enzyme interferes with the phosphorylation-dependent activation of nucleoside analogues used in the treatment of cancer and viral diseases
additional information
-
unilateral cortical stab injury causes a rapid and irreversible loss of the enzyme from neurons, accounting for a decrease in the overall enzyme expression, accompanied with a gradual increase in e-5NT-positive astrocytes, accounting for upregulation of the enzyme levels in the injured area. CSI induces dynamic changes in the expression pattern of e-5NT that modify the ATP/adenosine ratio and the extent of P1 and P2 receptors activation and, therefore, outcome of the pathological processes after cortical stab injury
additional information
-
CD73 is highly induced by ischemia and hypoxia, and increased expression in cardiac ischemia is mediated by a positive feedback loop involving adenosine

enzyme is responsible for generation of adenosine from AMP. Adenosine is involved in a number of cardioprotective mechanisms. TNF-alpha may reduce the capacity of human endothelial cels to produce adenosine by a decrease in activity of ecto-5'-nucleotidase. The loss of ecto-5'-nucleotidase may lead to decreased production of anti-inflammatory adenosine and retention of proinflammatory nucleotides
