Nucleoside diphosphate (NDP) kinase is an enzyme that transfers the gamma-phosphate of nucleoside triphosphates to nucleoside diphosphates. Besides this well-defined role, recent evidence suggests that NDP kinase may be implicated in a wide variety of essential cellular processes. In this paper, we showed that the NDP kinase of Drosophila exhibited protein kinase activity as well as autophosphorylation. Ovalbumin was phosphorylated with guanosine 5'-(3-O-thio)triphosphate (GTP gamma S) or ATP. Protein kinase activity was not detected in NDP kinase mutant, abnormal wing discs (awd). These results suggest that this activity could be one of the functions of NDP kinase essential for normal fly development, since awd gene is lethal.

UI MeSH Term Description Entries
D009701 Nucleoside-Diphosphate Kinase An enzyme that is found in mitochondria and in the soluble cytoplasm of cells. It catalyzes reversible reactions of a nucleoside triphosphate, e.g., ATP, with a nucleoside diphosphate, e.g., UDP, to form ADP and UTP. Many nucleoside diphosphates can act as acceptor, while many ribo- and deoxyribonucleoside triphosphates can act as donor. EC 2.7.4.6. Deoxynucleoside Diphosphate Kinases,GDP Kinase,Nucleoside Diphosphokinases,Nucleoside-Diphosphate Kinases,Diphosphate Kinases, Deoxynucleoside,Diphosphokinases, Nucleoside,Kinase, GDP,Kinase, Nucleoside-Diphosphate,Kinases, Deoxynucleoside Diphosphate,Kinases, Nucleoside-Diphosphate,Nucleoside Diphosphate Kinase,Nucleoside Diphosphate Kinases
