The junction-resolving enzymes

David M. J. Lilley & Malcolm F. White

Junction-resolving enzymes are ubiquitous nucleases that are important for DNA repair and recombination and act on DNA molecules containing branch points, especially four-way junctions. They show a pronounced selectivity for the structure of the DNA substrate but, despite its importance, the structural selectivity is not well understood. This poses an intriguing challenge in molecular recognition on a relatively large scale.
