'''ESCHERICHIA COLI RUVA PROTEIN AT PH 4.9 AND ROOM TEMPERATURE'''<br />

==Overview==

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.
