Abstract excerpt
During site-specific recombination by the gamma delta resolvase, four DNA strands are broken, exchanged, and religated. This exchange is carried out within a DNA-protein complex, the synaptosome, in which the recombination sites, res, are aligned. The domain of resolvase that binds to a res site is distinct from the domain that breaks and rejoins the DNA. We tested whether the catalytic domain acts on the res...
