Function

[NDKA_DROME] Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate.^[1] ^[2] ^[3]

Publication Abstract from PubMed

Nucleoside diphosphate kinase (NDPK) is a ubiquitous enzyme found in all organisms and cell types, which catalyzes the transfer of the phosphoryl group from a nucleoside triphosphate to a nucleoside diphosphate. The gene encoding for NDPK from Drosophila melanogaster was amplified from the genomic DNA. The recombinant NDPK (rNDPK) was overexpressed in Escherichia coli and purified to homogeneity by Ni-NTA agarose affinity chromatography, HiTrap SP HP cation exchange chromatography and HiLoad 16/60 Superdex 200 gel filtration chromatography. The gel filtration chromatography and analytical ultracentrifugation showed that rNDPK was a trimer in solution. The binding affinity of NDPs with rNDPK, measured by isothermal titration calorimetry, indicated that the purines nucleotides show higher binding affinity compared with pyrimidines. The rNDPK had a definite nuclease activity in vitro, which could cleave supercoiled plasmid DNA, but had no effect on dsDNA and ssDNA. Furthermore, the structure for NDPK was determined by using the sitting drop vapor diffusion method. In the final model, the asymmetric unit is made of three molecules, each of which consists of a four-stranded anti-parallel beta-sheets and seven alpha-helices. Sequence alignment and structure comparison illustrated that the simulated nucleotide-binding active site are conserved.
