Structural highlights
Function
[NDK_YEAST] 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. Required for repair of UV radiation- and etoposide-induced DNA damage.[1]

Publication Abstract from PubMed
Nucleoside diphosphate kinase (NDPK) catalyzes the transfer of the gamma-phosphate from nucleoside triphosphates to nucleoside diphosphates. In addition to biochemical studies, a number of crystal structures of NDPK from various organisms, including both native proteins and complexes with nucleotides or nucleotide analogues, have been determined. Here, the crystal structure of Ynk1, an NDPK from the yeast Saccharomyces cerevisiae, has been solved at 3.1 A resolution. Structural analysis strongly supports the oligomerization state of this protein being hexameric rather than tetrameric.
