== Publication Abstract from PubMed ==
 +
Nucleoside diphosphate kinase (NDPK) catalyzes the transfer of gamma-phosphate from nucleoside triphosphates to nucleoside diphosphates. The subunit folding and the dimeric basic structural unit are remarkably the same for available structures but, depending on species, dimers self-associate to form hexamers or tetramers. The crystal structure of the Escherichia coli NDPK reveals a new tetrameric quaternary structure for this protein family. The two tetramers differ by the relative orientation of interacting dimers, which face either the convex or the concave side of their central sheet as in either Myxococcus xanthus (type I) or E. coli (type II), respectively. In the type II tetramer, the subunits interact by a new interface harboring a zone called the Kpn loop as in hexamers, but by the opposite face of this loop. The evolutionary conservation of the interface residues indicates that this new quaternary structure seems to be the most frequent assembly mode in bacterial tetrameric NDP kinases.
