• PubMed Abstract: 
  

  Homologous recombination is crucial for genetic diversity and repairing damaged chromosomes. In Escherichia coli cells, the RuvA, RuvB and RuvC proteins participate in the processing of an important intermediate, the Holliday junction. The RuvA-RuvB protein complex facilitates branch migration of the junction, depending on ATP hydrolysis. The atomic structure of RuvA should enable critical questions to be addressed about its specific interactions with the Holliday junction and the RuvB protein.
