== Publication Abstract from PubMed ==
VirB11 ATPases are hexameric assemblies that power type IV secretion systems in bacteria. The hexamer of Brucella suis VirB11 (BsB11), like that of the Helicobacter pylori VirB11 (Hp0525), consists of a double ring structure formed by the N-terminal and C-terminal domains of each monomer. However, the monomer differs dramatically from that of Hp0525 by a large domain swap that leaves the hexameric assembly intact but profoundly alters the nucleotide-binding site and the interface between subunits.

A large domain swap in the VirB11 ATPase of Brucella suis leaves the hexameric assembly intact.,Hare S, Bayliss R, Baron C, Waksman G J Mol Biol. 2006 Jun 30;360(1):56-66. Epub 2006 May 11. PMID:16730027<ref>PMID:16730027</ref>
