The biochemical properties of the Escherichia coli UvrA tandem ATPase site mutants in nucleotide excision repair have been studied. In these and earlier studies it was found that ATP binding is required for protein-protein and nucleoprotein association reactions, whereas the dissociation reactions are driven by the hydrolysis of ATP. The self-association of UvrA to form the reactive dimeric species UvrA, is driven by nucleotide binding, but its dissociation from DNA requires ATP hydrolysis. Similarly, ATP binding drives those allosteric changes in DNA topology during UvrA,-nucleoprotein formation (Oh, E. Y., and Grossman, L. (1986) Nucleic Acids Res. 14, 8557-8571).
