The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate. We found that knockdown of nucleoside diphosphate kinases (NDPKs) NM23-H1/H2, which produce GTP through adenosine triphosphate (ATP)–driven conversion of guanosine diphosphate (GDP), inhibited dynamin-mediated endocytosis. oside diphosphate kinase is a multifunctional protein, with well defined functions in ribo- and deoxyribo-nucleoside triphosphate biosynthesis and more recently described functions in genetic and metabolic regulation, signal transduction, and DNA repair. Exhibits histidine protein kinase activity. the reaction catalyzed by NDK starts with the transfer of a phosphate from ATP to His117. The volumes in this authoritative series present a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The nucleoside diphosphate kinase D (NM23-H4) binds the inner mitochondrial membrane with high affinity to cardiolipin and couples nucleotide transfer with respiration. Here, we show that the association of nucleoside diphosphate kinase B (NDPK B) with the G protein βγ dimer (Gβγ) is required for G protein function in vivo. Nucleoside 5′-Diphosphate Kinase has been used in a study to assess inhibition of type I Fc epsilon receptor mediated Ca 2+ influx and mediator secretion in rat mucosal mast cells.

Nucleoside diphosphate kinases (NDPKs) are ubiquitous enzymes found in almost all species. Function i Major role in the synthesis of nucleoside triphosphates other than ATP. Nucleoside diphosphate kinase (NDPK) B can transfer a phosphate group from adenosine triphosphate (ATP) to any nucleoside diphosphate ( Fig. 13.2; Wieland, 2007 ). Deoxyribonucleotides in turn are used in the synthesis of DNA. Nucleoside diphosphate (NDP) kinase is a ubiquitous nonspecific enzyme that evidently is designed to catalyze in vivo ATP-dependent synthesis of ribo- and deoxyribonucleoside triphosphates from the corresponding diphosphates.

Nucleoside diphosphate kinases (NDPKs) are ubiquitous enzymes found in almost all species. Heterotrimeric G proteins in physiological and pathological processes have been extensively studied so far. Nucleoside-diphosphate kinases (NDPKs, also NDP kinase, (poly)nucleotide kinases and nucleoside diphosphokinases) are enzymes that catalyze the exchange of terminal phosphate between different nucleoside diphosphates (NDP) and triphosphates (NTP) in a reversible manner to produce nucleotide triphosphates. NDPK are found in all cells, displaying not much specificity towards the types of nucleoside bases and are capable of accepting nucleotides and deoxyribonucleotides as substrates or donors. Nucleoside diphosphate (NDP) kinase is the enzyme responsible in the cell for the phosphorylation of nucleoside or deoxynucleoside diphosphates into the corresponding triphosphates at the expense of ATP.

Nucleoside-diphosphate kinases (NDPKs, also NDP kinase, (poly)nucleotide kinases and nucleoside diphosphokinases) are enzymes that catalyze the exchange of terminal phosphate between different nucleoside diphosphates (NDP) and triphosphates (NTP) in a reversible manner to produce nucleotide triphosphates.Many NDP serve as acceptor while NTP are donors of phosphate group. Predicted to have nucleoside diphosphate kinase activity. Nucleoside diphosphate (NDP) kinases catalyse the reversible phosphorylation of nucleoside diphosphates to nucleoside triphosphates via a phosphohistidine intermediate [[1, 2]].The eukaryotic NDP kinases are also involved in the regulation of various functions including differentiation and cell proliferation [[3-5]].The expression level of human NDP kinase A (product of the nm23-H1 … Receptor Tyrosine Kinases (RTKs) play critical roles in embryogenesis, normal physiology and several diseases. And over the last decade they have become the Number 1 targets of cancer drugs. Transfer of the γ-phosphate is very fast (turnover number above 1000 s-1) and involves the phosphorylation of a histidine residue at the active site of the enzyme. In this paper, we report intrinsic ATP/ADP exchange activ-ity as a novel activity of 14-3-3. However, little is known about the structural elements involved in their function. The NME3 gene encodes a nucleoside diphosphate (NDP) kinase that catalyzes the transfer of terminal phosphates to equilibrate the NDP and NTP pools in a cell. Therefore, NDPK is the source of RNA and DNA precursors, except ATP. It catalyzes this formation by removing the 2'-hydroxyl group of the ribose ring of nucleoside diphosphates. The function of NDPK within primary cilia is most likely to regenerate GTP for microtubule turnover and for signaling systems, making it an important contributor to primary cilia structure and function.
