The binding mode of human nucleoside diphosphate kinase B to single-strand DNA.
In this paper, we studied the interaction of the human isoform B of nucleoside diphosphate kinase (NDP kinase B) with the nuclease hypersensitive element (NHE) present in the promoter element of the c-myc oncogene. The DNA-binding properties of NDP kinase B and other NDP kinases are compared and the nucleotide requirement for binding are discussed. Using quantitative methods, we identified the DNA-binding sites on the protein and we proposed a structural model for a complex of one hexameric NDP kinase B with an oligonucleotide.
