Medical Definition of Nucleoside-diphosphate kinase
1.
A phosphotransferase enzyme that is found in mitochondria and in the soluble cytoplasm of cells.
It catalyses 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 ribonucleoside triphosphates and deoxyribonucleoside triphosphates can act as a donor.
Chemical name: ATP:nucleoside-diphosphate phosphotransferase
