Science, 1996•science.orgThe Escherichia coli DNA binding protein RuvA acts in concert with the helicase RuvB to
drive branch migration of Holliday intermediates during recombination and DNA repair. The
atomic structure of RuvA was determined at a resolution of 1.9 angstroms. Four monomers of
RuvA are related by fourfold symmetry in a manner reminiscent of a four-petaled flower. The
four DNA duplex arms of a Holliday junction can be modeled in a square planar
configuration and docked into grooves on the concave surface of the protein around a …

The Escherichia coli DNA binding protein RuvA acts in concert with the helicase RuvB to drive branch migration of Holliday intermediates during recombination and DNA repair. The atomic structure of RuvA was determined at a resolution of 1.9 angstroms. Four monomers of RuvA are related by fourfold symmetry in a manner reminiscent of a four-petaled flower. The four DNA duplex arms of a Holliday junction can be modeled in a square planar configuration and docked into grooves on the concave surface of the protein around a central pin that may facilitate strand separation during the migration reaction. The model presented reveals how a RuvAB-junction complex may also accommodate the resolvase RuvC.
