In order to clarify the oligomer state of nucleoside diphosphate kinase (NDK) from moderately halophilic ${it Halomonas}$ sp. 593 (HaNDK), the crystal structure of HaNDK was determined by X-ray crystallography. The crystal structures of the wild-type HaNDK and the mutant HaNDK (E134A) showed a dimer and a tetramer, respectively. The higher ordered association of proteins usually contributes to an increase in thermal stability and substrate affinity. The change in the assembly form by a minimum mutation may be an effective way for NDK to acquire molecular characteristics suited to various circumstances.
