And Function

We have been interested in the structure and function of proteins involved in genetic recombinaton. The ruv locus on the E. coli chromosome contains three genes (ruvA, ruvB and ruvC) that are important for genetic recombination and DNA repair. The ruvA and ruvB genes form part of the SOS response to DNA damage and encode the RuvA and RuvB proteins. Together, RuvA and RuvB promote the branch migration of Holliday junctions in a reaction that requires ATP hydrolysis. Each protein plays a defined role, with RuvA responsible for DNA binding (and, in particular, junction recognition), whereas the RuvB ATPase provides the motor for branch migration. Sequence analysis has identified RuvB as a member of a superfamily of helicases, and experimentally it has been shown that RuvB, in the presence of RuvA, acts as an ATP-dependent helicase.When purified RuvB protein was incubated (in the presence of the ATP analog, ATP-γ-S) with covalently closed, relaxed dsDNA, double-ringed structures were observed on the DNA in the electron microscope (Fig. 1). The DNA must be passing through the center of these rings, since the rings are always aligned along a common axis.
